Hi! So my atari's video output is all garbage, or sometimes none at all. I recapped the sysem and did a console5 refresh kit and no difference. Tried different rf cables and used a known working psu. Any idea guys? Maybe the Tia chip or maybe something simple? Thanks!!

I'm fairly new to the ST, but I picked up 3 STs, in a lot, recently. I got a 520stfm, a 520stm, and a 520st. I didn't get any monitors, or video cables, with them, though. Given that situation, the first thing that I did was to make up a DIN-13 to composite video + audio cable. The quality of output I got from that was acceptable (but not great) at low res, and terrible at medium res. Looking to improve my output, I bought a an NEW v2.0 Atari ST DIN13 to VGA Adaptor Low-Medium/High Switchable with Audio Out and, after reading that my Extron RGB-HDMI 300a was capable of going beyond the spec of 30 kHz, I tried it out. I think that the results speak for themselves. You can see some jailbars, particularly in high res, but if I take a bit of time to adjust the phase, those should go away. These images are the defaults, with zero tuning. - Alex

i saw this video on youtube https://www.youtube.com/watch?v=0yKwJJw6Abs and i thought, i can totally do that on the TI.. so.. 10 D$="FF" :: FOR D=65 TO 65+8 :: D$="00"&D$ :: CALL CHAR(D,D$) :: NEXT D :: FOR B=1 TO 10 :: PRINT "F";"E";"D";"C";"B";"A";"A";"B";"C";"D";"E";"F";"G"; :: B=1 :: NEXT B i had to print each character individually to get the required screen movement.. Here's xbasic, and compiled.. WAVE is normal extended basic, -X is compiled but loads in extended basic, and -E is EA5 load. looks pretty slick compiled some small screen glitches likely because I'm running classic99 in Wine on a linux pc..

Hi there, I have an unusual collection for you all to see. Back in 2016 I made a simple challenge for myself: collect one of every GBA Video cartridge that exists. And holy crap, some of these were hard to find. Most can be found for very cheap, usually in the $5-$10 range, but as you will see, there are some major exceptions. I actually completed this collection about a year ago, but never got around to posting any pics. For those who don’t know about GBA Video, effectively what they were are special white GBA cartridges containing 45-ish minutes of incredibly low-quality video, to be viewed on the Game Boy Advance. When I say low-quality, I mean it makes old 240p YouTube videos look good by comparison. But in 2004-2006 when they were released, most people didn’t have a device in their pocket capable of playing video like we all do now. So at the time, it made sense. Nowadays they’re pretty much obsolete - better options for viewing videos on the go exist, and have existed for quite some time. Now you might be asking, why would I want to get a complete collection of an old, obscure, and obsolete video format? Simple: because I’m completely out of my mi- er, I mean a dedicated collector! I had a few of these cartridges back when they were new, so there’s an element of nostalgia to it, but mostly I did it because I've never seen someone attempt it before. Plus, I didn’t think it would be too difficult. I mean, how many of these cartridges could they possibly have made? Hoo boy. To my knowledge, there are around 35 different GBA Video cartridges that exist. I say “around 35”, and put the asterisk in the title, because I’m still not 100% sure if this is complete. I did a lot of searching with Google, trying to find a complete list of which cartridges were released, but I couldn’t find one. Each list I found was different, and they were all missing titles - even the official GBA Video website doesn’t even have half of the damn things they released listed. So I made my own list. I put a lot of effort, and a lot of hours into cataloguing every GBA Video cartridge I could find evidence of, and these are the results. Without further ado: pics! This is all of them. I’ve sorted them by series. The ultra-rare ones I keep in plastic cases at the bottom. Apologies for the glare - I’m a bad photographer. I’ve added text to indicate what they are. These are the one-offs - shows that only got one volume. And yes, I’m aware I have two copies of the Kids Next Door cart, I intended to only include one in the pic, but I’m too lazy to re-take it Okay - seriously, who asked for 6 different Cartoon Network Collection cartridges to be released? This is ridiculous. And what's with these names? It goes Volume 1, Volume 2, then Special Edition, Platinum Edition, Premium edition, and Limited Edition. And yes, they’re all different. Good lord. There were 4 Pokemon cartridges released, 2 Fairly Odd Parents, and 3 SpongeBob. The only one of these that was difficult to find was SpongeBob Volume 3 - I had to scour eBay for awhile before I found it. I don’t understand why the first two SpongeBob carts have the same exact pic while the third is different, but whatever I guess. 6 Cartoon Network Collection carts but only 3 Nicktoons Collection carts, with the third being extremely rare (I’ll show it off later)? Weird. The four on the bottom are the only movie cartridges released that I know of - and yes, they actually contain the full movies, but the video quality is horrible and at a very low framerate. Now we’re getting into the rare stuff. Super Robot Monkey Team Hyper Force Go - a show pretty much nobody has heard of, which I assume is why this cart is so rare. It has a 9/10 rarity level on NintendoAge, but I only paid about $50 for it. It was the only copy I could find on eBay at the time. I showed off both of these in a previous pic, but I’m posting them again because they were ridiculously difficult to find. The 2-in-1 cartridge, believe it or not, actually contains both full movies. To be honest I’m stunned that they fit on a single cartridge. Disney Channel Volume 2, I got from JJGames. It was out of stock for months, and when they finally got one in stock, I snapped it up as soon as possible. NintendoAge doesn’t even have a rating for it. I have never seen a copy of it on eBay. Does that mean it’s ultra-rare? To be honest, I have no idea. I’m just glad I found one. This one took a long time to get ahold of. 7/10 rarity on NintendoAge. I bought it for about $50 on eBay, but again, it was the only copy I could find so I didn’t have much choice. There are a few copies on eBay right now, and holy crap, apparently it's worth a lot more than that now. This one was a major pain. It was the final cartridge I needed to complete my collection. It took me over a year before I finally found it on eBay, and it just happened to be in a lot of games someone was selling. I convinced the seller to sell just this cartridge to me, and they only asked $25, which I was happy to pay. At the time of writing this, there are only a few copies on eBay, and they're asking an insane amount of money for them. Oddly enough, it only has a 5/10 rarity (not sure if that's accurate). It’s worth noting that there may be one more cartridge out there: a 2-in-1 movie cart containing both Shrek and Shrek 2. They definitely released both of these movies in a single package, as you can see in this pic: However, I don’t think there was ever a single cartridge containing both movies in one. I’ve seen CIB listings for this release on eBay, and rather than a single cartridge they just had the two separate cartridges in a single box, both of which I already have. I have yet to see a single piece of photographic evidence that another 2-in-1 cartridge exists, and if anyone can prove me wrong, I’ll gladly pay top dollar for it. That concludes my GBA Video adventures up to this point. Thanks for reading! Edit: Full list of released carts and their rarity: 2-in-1: Shrek and Shark Tale (movies) (Rarity: unknown) All Grown Up!

Hi; So I hauled out my 8-bit collection (that has been modded for various reasons back when I used it heavily back in the '90s). I have forgotten soooo much! This 8-bit stuff got me through a dissertation, online database searching and early attempts at running a profession-related BBS before the Internet was ubiquitous. Current problem. I'm trying to efficiently figure out what to do to resurrect a 130XE that currently only boots to a blank green screen. I noted that a different computer (Also Atari 8-bit) booted to green screen when the ribbon cable for the keyboard was badly inserted (a corner was folded over itself...straightening that out allowed it to boot correctly, but that was not the problem with the unit at hand). First question: I have a pretty horrid/beat up 65XE that I was thinking I might scavenge for parts/chips, BUT other than memory are the 65XE chips the same as the 130XE? Next question: Is there a step-by-step logical process for teasing out the most efficient process for diagnosing/repairing the green screen issue? Thanks Stuff I have on hand... CSS Black Box with Floppy Board (Bob Puff was my main go-to guy back in the day!) SpartaDOS X with R-time-8 cartridge 130XE with 320 RAM upgrade/Multiplexer OS (in good working order) 130XE with a ROM board/switch that can switch/boot between 3 different chips (this is the machine with the problem) 800XL standard/good working order 65XE with horrid case and keyboard with many dead keys (I might be brave/foolhardy enough to try and desolder this for parts). 1050 disk drive XF551 disk drives (2) Hard drive with various Sparta/MyDOS boot partitions and utilities. Various game cartridges and 8-bit software mostly on 5.25 disks.

This is now a "quest" -- and way more interesting to me than an adventure game! I've been doing a little research on the 600XL video issues, trying to find a "Quick and Easy" solution such as the excellent information in the "Quick and Easy Video Upgrade for the 800XL." http://www.atariage....rade-for-800xl/ That thread actually contains a reference to an article on the 600XL: (BTW, the author of this also did an article on bringing the ram in a 600XL up to 64K.) http://atrey.karlin....i/600xlmon.html This method is way easier than SuperVideo 2.1. Has anyone done this mod, and does it give good results? I wonder if it can be "tweaked" to improve the results? There is also the Best Electronics 600XL kit shown on this page: http://www.best-elec...800xl.htm#600XL Has anyone done the B.E. kit mod, and is it the same as the mod shown above? Or is the BE mod a kit of missing parts to make the 600XL video functional through a normal monitor jack? Does it provide good results, or do you then have to "mod" the results to get good video? (If the 600XL video ends up looking like a stock 800XL, that's probably not a good thing.) -Larry

Hello Atari owners and modders. I'm trying to add an audio / composite output on my "new" atari 2600 (NTSC 4 switch), but I can't obtain any image... The console worked yesterday with RF output, but with no sound and a really weird/dirty b&w image. That's why I decided to add an A/V mod to permanently solve the problem. I think I choose the cheaper solution: 2 resistances and 1 transistor, similar to the easier-7800-composite-video-mod My circuit is the same as the solution proposed by brighty83 for a PAL version here (down of the page):http://retro.mmgn.co...ari-2600-AV-Mod I found the same cicuit on ebay, sellers detail the process on their installation guides for NTSC versions: http://rover.ebay.com/rover/1/711-53200-19255-0/1?ff3=4&pub=5574883395&toolid=10001&campid=5336500554&customid=&mpre=http%3A%2F%2Fwww.ebay.com%2Fitm%2FAtari-2600-7800-Composite-Video-Mod-Upgrade-Kit-DIY-%2F300592126324 (see Installation Guides for atari 2600 4 switch) or http://rover.ebay.com/rover/1/711-53200-19255-0/1?ff3=4&pub=5574883395&toolid=10001&campid=5336500554&customid=&mpre=http%3A%2F%2Fcgi.ebay.fr%2FAtari-2600-A-V-Composite-Video-Mod-Kit-NTSC-PAL-DIY-%2F181042624250%3Fpt%3DLH_DefaultDomain_0%26hash%3Ditem2a26fb36fa installation guide: http://www.filedropp...stallationguide (page 10 for NTSC 4 switch) Here is the circuit (sorry for the poor image quality): Video out and GND ---> Video RCA Audio out and GND ---> Audio RCA As mentionned on guides for NTSC 4 switch, I removed the RF box, Q202 and R209: The sound works well, but no images, it's so sad... I don't know what to do, and I'm dying about playing with it, in good conditions I mean. Some of you tried this mod? any idea ? Fujisama

Hi. I recently bought an Atari Jaguar of eBay. It is PAL. It seems to power on and shows a green light. But when I hook it up to the TV, I see a distorted image (what you see when you don’t insert an Atari 2600 cartridge properly) I’ve been told by someone that the console is working as it should and the image I see is caused by the PAL system being used in an NTSC country. What do you think? By the way, I am using the AV signal. Is there something I need to buy to get it working? Thank you!

Now let me start by saying I have done extensive research into this. I'm aware of all ways of connecting an atari to a modern TV, but what I really need is an opinion on wether my specific issue is my own stupidity, or the TV just won't do it. The TV is: http://www.vizio.com/e65c3.html I'm using the RCA to coax adapter. Directly connecting it to the TV via coax and switching to this input yeilds no result. I connect the Atari to the input of a VCR, then connect the composite output to the TV. I can get the VCR to play tapes over the TV, both video and audio, but I cannot get the Atari to display through it. Is it possible that the VCR is not a good enough demodulator/converter for this modern of a TV? Is there usually some menu option you need to tinker with to get a digital TV to detect the input (either directly or through a VCR). Is it possible that this TV just doesn't have the capability I need to play the Atari on it?

Hey everyone. Had a quick question for those of you familiar with Hardware because I really am not. i have a video issue with only certain homebrews and hacks. Original release 2600 games play fine, all 85 or so i own. It doesn't happen every time with the effected games, and when it does happen usually taking the game out and reinserting it once or up to 3 times will make the issue go away. could this be a power issue? Capacitors or something inside the system failing? Or simply just RF interference of some kind? I'm using a light sixer on a CRT through RF. I'll post a picture of one of the affected games and then a couple of pictures of regular games playing fine. thanks alot everyone.

Hello everyone. I am having some difficulty with an Atari 7800 that I picked up that I hope, with the help of this community, we can figure out. The unit didn't have a power supply so I picked up a new switcher from best and it checks out fine and powers up the unit. The problem that I am having is the picture has a lot of static, you can barely make out the image but it has color and responds to control input. The second problem is the sound which is nothing but static, no game sounds what so ever. I did clean out the cartridge receiver on the board with 91% alcohol and a cloth over a credit card. I'm connected through an rf coax adapter using an rf cable. I've tried different cables and adapters, tried different cleaned 2600 games since I don't have any 7800 games yet, switching through channels on both the console and the tv, re-scanning channels on the tv with a game running on the console, running through a vcr to tv using the composite and then the coaxial output of the vcr, and lastly using an old tube tv. The ohm resistance on the rf output is 1 with a the meter set at 200 while my 2600 has an ohm reading of 100 with the same setting. I use to get a reading at .18 with it set above 2k but now it's just reading 1. Best electronics says it sounds like a motherboard issue and the av mod likely wouldn't make a difference. I'll try to upload an image of both sides of the board.

Hello all, long time reader, first time poster on the forums. I recently picked up a junk Coleco Telstar Combat system made in ‘77 for a couple dollars. It was pretty roached, but it’s a rather obscure system so I couldn’t pass it up. However, after getting it all cleaned up, I plugged it to my TV to test it out, but all I got was static and no signal. I tried many times turning the system off and on but mostly no signal would appear at all. Sometime a staticky signal would fade in and out, but it was very inconsistent. Once, I even got a vague image of the actually game screen to appear for a few seconds. I’m fairly confident that the video cable coming from the system itself is not the issue and I have it hooked up to a known working RF switch that works well with my Atari 2600. So, I opened the system back up, removed the RF shield, and began to adjust the RF inductors (I’m using a modern tv). ( I attached pics for reference) There appears to be 2 RF inductor adjustments under the shield, and a screw adjustment at the top right corner of the board. I started adjusting the orange (bottom) inductor but that only caused the video to go from no signal, to staticky image, back to no signal. So I tried to adjust the white (top) RF inductor, but it wouldn’t budge. Upon further inspection, I saw the slot inside this inductor had several cracks. I desoldered the inductor from the board to examine it further, but couldn’t get it to budge. After resoldering it back on, I still have the same issue, however, the static signal seems to become more and more scarce, leaving me with no signal as I fiddle more and more with the inductors. I also tried adjusting the screw adjuster to no avail, but I’m not really sure which RF adjusters I should/need to adjust. Would the cracking in the inductor be enough to inhibit the video signal completely? Is there anything else that could be causing this issue besides the inductors? I have a rather limited knowledge on electronics as I have only been attempting retro repairs for about a year and a half, so any new nuggets of knowledge are greatly appreciated! This is a really neat and rare system that I would like to have working in my collection. Feel free to ask questions if something isn’t clear. Thanks in advance! (Note: I have the same problem regardless if I’m using batteries or the power supply).

Well, I'm diving back into real TI hardware and unfortunately my luck with it is like with nearly everything else - if it wasn't for bad luck I'd have no luck at all! Anyway, I'm not here to pity myself, but would like to know what the issue is with one of the TI-99/4A's I recently picked up in as-is condition. I've attached a picture of the boot screen which shows a lot of garbage and obviously isn't working properly. Is this a video RAM problem, the display chip, or something else? Thankfully I did get a hold of one working 4A (the 4 also has problems - it powers on but has nothing but snow on the screen and a weird high pitched static / white noise going on so I don't know what's wrong with it), a speech synthesizer, and a bunch of carts including a few rare ones. Of course, it's the carts only - no boxes or manuals, but I'm still pretty happy with what I've picked up so far, along with my notations for my own reference. # in parentheses is how many I have of each if more than one: Adventure - TI (3)(cartridge only) Alpiner - TI (3)(speech) Buck Rogers: Planet of Zoom - TI (speech) BurgerTime - TI (flaky) Car Wars - TI Congo Bongo - TI Diagnostic - TI Disk Manager 2 - TI (4) Editor/Assembler - TI (3)(requires 32K)(cartridge only) Jawbreaker II - TI M*A*S*H - TI (speech) Mini Memory - TI (3) MunchMan - TI (2) Parsec - TI (speech) Return To Pirate's Isle - TI Speech Editor - TI Star Trek: Strategic Operations Simulator - TI (speech) Super Demon Attack - TI Terminal Emulator 2 - TI (6) TI Extended BASIC - TI (5) TI Invaders - TI TI WRITER Word Processor - TI (cartridge only) Tombstone City - TI Tunnels of Doom - TI (cartridge only) Ambulance - Funware Defender - Atarisoft Disk Fixer V2.1 - Navarone (requires 32K) Frogger - Parker Brothers Jungle Hunt - Atarisoft Micro Pinball II - DataBioTics Miner 2049er - Tigervision (2) Pac-Man - Atarisoft (flaky) PDM-99 (Peripheral Diagnostic Module) - CorComp Pole Position - Atarisoft Speed Reading A - Navarone (flaky) Super Extended BASIC - ? Wordwriter - DataBioTics Could have been better, but overall, I'm glad that I got at least one working machine with which to start over. I'll have to look over the threads here to see what the best path forward would be for getting 32K RAM added, as well as storage.

The title pretty much says it all. Has no one attempted/succeed at this? Google searches are fruitless. I feel like, out of several billions of people alive today, I may be the ONE person looking to output my Intellivision via Component. ??‍♂️ I'm weird like that, I guess.

I made a video talking about deciding which games to keep in my genesis collection along with game video capture from my system. Let me know which games I should keep! https://youtu.be/kBkkrPVn5-A

This is more of a feeler listing as I would like to find out if it's possible to get a G5 1.6GHZ compatible AGP video card with at least 128MB VRAM(256 preferred, but dependent on cost) for a more reasonable amount of money than the +$100 listings i've seen on eBay. All things being equal, I would rather not dump a log of money into a machine that has somewhat of a checkered history as far as it's reliability is concerned. I don't have any hardware that I could use to flash an AGP video card myself, so I can't just buy a PC ROM card and flash it. As long as it works with my system and preferably has a VGA port in addition to DVI, I wouldn't mind a flashed GPU if it meant it was a bit cheaper. I was hoping to stay under $30 shipped if at all possible. Thanks for reading.

So I've got myself a new, or to me at least, Atari 800XL PAL (Manf. Taiwan) version that seems pretty much untouched. I've just built an SIO2PI, and SIO2Arduino to start getting software on to it but with regards to memory and video upgrades I'm a bit lost with all of the options mentioned in the forums. Firstly with the video. I've got an s-video to VGA converter which I want to use, and I've seen a lot of recommendations to go the way of UAV but as I understand Bryan's got a lot going on these days and won't be producing more boards until next year at the earliest. I took a quick look at the s-video modifications thread which started in 2009 but it's really hard to figure out what the latest suggestions/methods are in this thread with a number of changes made in the last few years. Unfortunately Sophia is out of price range for me at the moment, especially with shipping and import taxes where I'm located. What are the options for improving the video signal these days? Homebrew/DIY preferred over trying to get boards into the country. Secondly, I'd like to upgrade the memory a little. Again, U1MB seems to be the go for solution these days but though the board is only $80 I'm looking at another $100 on shipping and customs fees. Looking at the stuff I want to do, 256K would be sufficient but I've no idea if there's any highly compatible, reasonably straight forward upgrades currently available, or again homebrew/DIY. Soldering is not an issue so not necessarily needing plug-in solutions. Anyway, great to be accepted into the community; the last one I was part of was the FaST club in the UK back in the 90's but feel more at home with my 800XL on my desk. Any help or advice on getting started also gladly accepted.

I just acquired an Atari STFM with a SM124 and SC124 monitor. When starting it up for the first time, the monitor does power on as well as the computer, it accesses the floppy drive, but the video output is not working. See attached photo and video. The SM124 monitor has the white line but the SC124 has no video at all. Not sure if it's a monitor problem or an internal video card problem. Any ideas? thanks AtariSM124monitor_problem.mpg

Regarding a recent discussion on the various aspect ratios available to the stock console (or emulations thereof), there seems to be some clarification needed on what the actual aspect ratios are of the original TI output (both 60Hz and 50Hz). I say "needed" because, firstly, this info is very hard to find, and, secondly, there is a belief among some that the TMS9918, at least, has a 4:3 aspect ratio addressable pixel area with square pixels. This is not true, and, consulting the datasheet to solidify the numbers in my own mind, it is clear that neither the TMS9918A nor the TMS9929A employ use of square pixels. Most of the emulators I've seen use square pixels. Hopefully these numbers will be of use to someone else at some point. On page 5 of a document entitled TMS 9918A 9928A 9929A VDP Preliminary Specification 1981, there's this section: The hasty handwritten figures aren't mine; that's how I found this document on the web, and boy, it is not an easy document to find. Here it is for posterity, and, from this datasheet, plus the F18A documentation here, I've put together a side-by-side comparison of the different aspect ratios offered by each VDP. Remember that all of these are designed to send their output to a 4:3 screen. With the TI's addressable pixel area being 256x192, or also 4:3, you may think that this is a great match: 4:3 addressable area to a 4:3 screen = 4:3 aspect ratio. But no, the timings of the various analogue video systems have to be respected, so extra pixel rows and columns are required to border the addressable area. The 60 Hz VDP outputs an area of 284x243, although only 256x192 pixels are addressable, while the rest of the 'pixels' are set to a solid background colour. The 50 Hz VDP outputs an area of 284x294, although, again, only 256x192 pixels are addressable. Of course, there are no actual 'pixels' in the border area, but the pixel clock is running, nonetheless, and a pixel width is used as a reference in the above datasheet for the amount of vertical or horizontal space occupied by this area. The F18A outputs square pixels, as asserted by the chip's designer. However, square pixels (1.333:1) are a slightly different 'squeeze' to what you'd get from an NTSC console (1.52:1), and very different to what you'd get from a 50 Hz console (1.82:1). Given the numbers provided by the creators of all three products, the side-by-side comparison of aspect ratios looks like the following diagram: Personally, I most prefer the NTSC shape. It's a nice fit for the available screen area. The 50 Hz (PAL) that I have access to I.R.L. is too squashed in the vertical direction (or "short"), while the F18A is too "tall" for my liking. That being said, my previous sentence is merely my opinion, and not a slight on anyone nor any reason to take offense. I'm just stating a preference, and y'all are welcome to your own! Also, please note that results may vary, depending on the knobs and settings on your old CRT. On some of them, you can adjust H-WIDTH, and even V-HEIGHT is often a possibility. Both of those will alter the aspect ratio by squeezing or stretching the image. LCDs do a better job of remaining faithful to the input signal and not chopping anything off, but, if you fiddle with the menus, you can usually override that as well, depending on the monitor. If I've made any errors, please let me know!

Hi, everyone. I completed the Saundby S-Video mod on my 7800. I now have it plugged into my LCD screen. I know my choice of TV could be the problem, but before I go find a CRT, I figured it was worth posting my problem here in case anyone has a quick answer. The video is wavy, particularly noticeable at the edges of lightly colored objects. Here's a YouTube video of the problem. https://youtu.be/dcwT4k0Y16U Any ideas? Thank you!

I just had to post here- in case there is anyone who hasn't yet watched Peter Dell's amazing Videos on programming the A8 in machine language: https://www.youtube.com/playlist?list=PLmzSn5Wy9uF8nTsZBtdk1yHzFI5JXoUJT I have futzed around the A8 for years, read some books about assembly but I never really understood how you do it (eg - knowledge of the Atari chips, memory map and how you use them to actually do some simple things in assembly). Peter shows you. His series is amazingly concise yet logical and he builds nicely thru the series and covers all the basic parts of the Atari. For me it's been the first time that I've truly caught on as to what is going on in there, and how the chips are working in concert to make this machine run. I've done a fair bit of Modern Ruby/Python/Node programming for networking apps- and of course it's nothing even remotely like that. It's so worth spending the time - just to learn how amazing the Atari hardware, os and chip are and how brilliant the designers were when they sat down years ago and decided on how to build this machine. Those guys were true visionaries in terms of building a flexible system to be used in ways they hadn't even thought of. And of course his http://www.wudsn.com/index.php/ide/installationWUDSN is a one-stop installation to start using assembly on a modern PC and run it on the included Altirra emulator with one click. Amazing. So, thank you Peter if you are around here anymore.

Hello Everyone! I haven't been able to find this specific issue on AtariAge, Youtube or through Google. Maybe if I knew the correct term to describe the issue I'd find ten thousand solutions, so I'm a little nervous mentioning my issue here. Here's the short version: I have a heavy sixer that consistently outputs video in black and white with many well spaced vertical lines evenly spaced throughout the image. It looks like this: Excuse the blurriness of the image, that's my shaky hand. The image on screen is actually quite crisp. Note that this is with the color mode selected, but the display appears in black and white with vertical lines throughout. The signal itself appears to be quite strong, it's not too fuzzy and doesn't have much of any interference. The getting longer version: The above image is in 'color', the actual black and white mode looks to be what you'd expect: I spent a week working on the issue, I cleaned all the slot and cartridge contacts, replaced one then the other 22uF Capacitor, I replaced the 2200uF Capacitor, then I replaced the 5v regulator. Using a multimeter I took a few samples and the numbers are in the range that I expect. All this time I was using a Coaxial F Plug to go to the TV. Then I thought back to a long time ago when I remembered the system actually outputting color and (guessed) that maybe I was using the original RF switch. So I tried that, and guess what happened? Color. So I thought to myself, I didn't know a F Plug would have this effect, but I'm so happy it's working I'll call it a week and put the system back together and consider myself lucky. But once I put the system all back together and tested it one more time with the RF Switch? Back to Black and White with vertical lines. And let me tell you, in the week I was working to fix the problem I must have tried the system 30 times, five different games on two TVs (An HDTV is pictured, the other is a 1990s Trinitron). Every time was black and white with vertical lines. It seems like so much of a coincidence that as soon as I tried it with the RF Switch everything worked great, but alas it was only one time. At this point, I'd be happy just to hear someone else say they've seen this issue before. As I said before my esteem is already low because my searches have been fruitless. The video cable looks in great shape from the box all the way to the tip. Games work immediately when I turn the system power on every time. Are there more places I should check the voltage? Any other suggestions?

Hi Guys, I'm making a video on TIPI tomorrow. Is there anything specific (or not listed below) that you would like included in this video? Here's what I'm planning so far (not necessarily in this order): 1. Brief Intro 2. Close-up of the TIPI + 32k Sidecar + RPi / assembly / Install (Quickly) 3. Case available for the TIPI + 32k (recently released) 4. Creating the TIPI Disk Image for the RPi 5. How to configure the TIPI to your WiFi Network 6. How to use the built-in Telnet to connect to a BBS 7. How to connect a Mouse to the RPi+TIPI and use it with TI-Artist (Thanks M@) 8. Demonstration of Chatti, Chess and SNEK (Thanks Electric and Omega) 8. Saving programs to the TIPI (TI-Basic / XB) 9. Using the web administrator to manage files (view, map to disks, etc.), how to UNC (\\tipi) into the RPi to directly copy folders to TIPI share. 10. Where to purchase a TIPI, 32k Sidecar, RPi and Case Anything that I've missed? Hope to film the missing pieces tomorrow, edit and get the video posted soon. But, before I get into full editing, I wanted to make sure I covered everything that others might want to see. Please comment below Jon ps. You can find other TI videos I've created in my signature, if interested...
