I made an interesting discovery today with my SIDE2 Cartridge. First some basics - I own a 600XL in stock configuration, with 1064 expansion, a 800XL in stock configuration and my "daily driver", a 130XE that I freshly extended with a U1M from Lotharek this week and that has a built-in a SIO2SD that I added a long time ago. I also own a SIDE2 cartridge since 2015, but the SIO2SD i built into the 130XE was always "good enough" and familiar, so I never used the SIDE2 much. Yesterday I decided to give the SIDE2 a go together with the U1M and updated it's really ancient firmware with the most recent one from FJC. Had a few issues with that because UFLASH didn't like the Cart at first, but the alternative way with SIDE2.COM worked fine and after the update UFLASH also started to work. Flashed the SIDE2OSS ROM. So far everything works great on the 130XE with U1M. Today I wondered what happens if I use the SIDE2 with the other machines and discovered an interesting difference between the 800XL and the 600XL with 1064. As I had not used both machines for a longer period of time this was intended to also test the machines to make sure they still work fine - I loaded the CF Card with games and digged the machines out of storage. I am aware that the 64K of a stock machine is only enough for basics, so I didn't expect too much. I first tested the 600XL and everything worked surprisingly well - I could run games using the SIDE Loader. I tried SpartaDOS X - everything was accessible and I could even run SIDECFG and switch the ROMs: Tried UFLASH and got a "179 Memory conflict", but that was expected. If I remove the 1064, the SIDE2 is not able to run at all. So far, so good. The 600XL seems to work fine. Then I tried the 800XL and to my surprise it behaved differently - the SIDE Loader was not able to detect the CF card properly: I then switched to SpartaDOS X - after turning on the machine, drivers were loaded, but no partitions visible or accessible: If I reset the machine with the reset button, I can access the CF card and the partitions on it: But trying to run SIDECFG gives me a "179 Memory Conflict" here. I first thought that the machine might have hardware problems, but it works fine otherwise - the builtin memory test is fine and I was able to run several games from an external SIO2SD without problems. So the hardware of the 800XL also seems to work fine to me. But now I'm lacking an explanation, why the machines behave differently. The only idea I got after a lot of googling: Does anybody know if the SIDE2 is able to use the 16KB RAM of the 600XL that the 1064 disables by default? From my understanding it should be the only difference between the two machines and 16k more memory might really be the big difference here. Otherwise I am lost what the problem of the 800XL is, that the SIDE2 behaves so different with the same amount of memory while everything else seems to work. Would appreciate any help in getting this sorted out. The 600XL and the 800XL were my first two computers, so I want to keep them in stock configuration and working as good as possible.

Dear Atari fellow, I wonder in what form the 1985 special packs were sold in the UK. On 16 February 1985 PCN announced that packs would be available in the UK, to clear the warehouses before the arrival of the 130XE. On 27 April 1985, Silica Shop offered 3 different packs. (see details below) The question is: what did these packs look like? Was it just a promotion, the components of the packs were just sold as normal, but with a discount? Were they put together in a special box (like the "Dixon exclusive" packs later with the 65XE)? Was there a special box, bag, packaging? I ask this question to complete the Atari 8-bit FAQ. I know there were other packs, later, or in other countries. I'm specifically trying to get some information about the 1985 UK packs... On 16-Feb-1985, an article in Personal Computer News reads: "Depreciation seems to start work on the 800XL before it even crosses the counter. The machine's price was virtually halved by Christmas last year, and two packages due to be put together this month effectively bring it down again. Its price at the moment is 129 GBP. The first package will give you an 800XL, 1050 disk drive, Home Filing Manager and a disk-based adventure for 249.99 GBP. The second puts together the 800XL, a 1010 recorder and Pole position for 129.99 GBP. [...] If dealers start to split these packages [...]" On 27-Apr-1985, a full page ad of "Silica Shop" - one of the largest Atari reseller in the UK - lists: Atari 600XL entertainment pack 600XL + Donkey Kong (cart) + Qix (cart) + CX40 = 69 GBP Atari 800XL and recorder pack 800XL + 1010 + Pole position & demo program (assumption: cassette TX8034, "Pole position" & "Atari graphics demonstration") + Invitation to prg #1 = 129 GBP Atari 800XL and disk drive pack 800XL + 1050 + Home filing manager (diskette) + The payoff (diskette) & demo program (diskette) = 269 GBP Thanks in advance for your contributions.

On the NTSC Atari 600XL the only video output is RF and the picture quality is really not very good, at all, not in the least, bad. So I thought maybe, if I want to use this 600XL for anything more than a prop, I might want to replace the video with something better. After looking around I chose the UAV by https://thebrewingacademy.com/ due to it’s simplistically and it’s cheap at only $30. Plus it has one of the best pictures I have ever seen for a composite output. Installation: (My work area) NOTE: This information covers the installation of the UAV composite and the way I installed it for NTSC 600XL ONLY. There are other ways to install the device but this is the way I choose. I am not responsible for any problems you may have following these instructions. I tried my best to make as clear as possible. So there. The UAV comes several ways. I chose the pre-built drop in as it’s the simplest. The package comes with all you need to drop in install (except what’s needed for sound). FYI: here is the link to the manual: http://www.thebrewingacademy.net/UAV_manuals.zip The manual covers ALL the various machines that the UAV can be installed in giving not too much space for any one type. Read over the manual but don’t expect a step by step install. Now my installation. Of course the first thing I did was open up the computer (seen in picture above). The blue wiring is the 64k upgrade I previously did. The UAV is a little board that plugs into the slot of one of the chips you remove. Then you add some wires and 3 solder points (if install like I did). Here is the board. I put tape over the top and bottom because there isn’t much clearance in the 600Xl and didn’t want to chance a short. Top view. Bottom view. Notice an extension on the bottom pins. This is so that the chip will clear a line of resistors just in front of the chip. I found the extension to be a bit unstable so later I took it off and the board set just fine. Remove the chip U19 as this is where the board will be plugged in. The UART socket is in the black box. Notice I have put electrical tape around the resistors in front of the plug. I found that playing around with placement of the board these resistors tended to want to push against each other and short. The tape kept that from happening. Next to the UART socket I have a green wire soldered to a resistor. This wire will be attached to the UAV board later and supplies the color signal. This is the board plugged into the socket. You will be attaching wires to that green header in a bit. Notice the jumpers I had tape on in a previous picture. Refer to the manual on the placement of those jumpers for the 600XL. The board does not come with the jumpers set for the 600XL so you will have the change them. Little trivia, to the left you will see places for several missing components. This is the missing composite circuitry NOT found in the NTSC version of the 600XL. For my installation I removed the RF module and the channel selector switch. Location is next to where the channel switch was. This is where I take the sound off of. I soldered in two pins to plug the sound cables into for easy removal. Pin on left is ground. OK, I know I’m going to get a lot of gruff for this but I didn’t solder in a 5 pin plug for this install. Reasons, I plan to only use the composite so most of the other pins would not have been used since I had no way of utilizing the S-Video capabilities of splitting the Luma and Chroma. Also I already had a dual RCA plug. Anyway, here is where you plug the wires into the board and the sound. I cut holes for the RCA plugs and mounted the board on the back of the 600XL where the RF plug was. AND IT WORKS. The finished product. That’s it. That’s all there is to installing the UAV the way I did it. Hope this helps. Good luck.

Hi everyone, Not sure if Redhawk666 is still active here, but I built his brilliant SMD s-video/composite board and installed in in my NTSC 600XL - and expanded his installation instructions to boot. Here's my fork of his project (I've opened a pull request, but not sure if he's actively looking at GitHub to merge my instructions). I've included an image and screenshot below - amazingly clear and interference-free picture that could easily be fed into an s-video-to-HDMI converter (my old monitor has an s-video input). I also had to order 5 boards from my supplier, but can only use one, so I'm wondering what to do with the other four? You really have to be adept at SMD soldering (and desoldering - haha), since the diode is SOD-323 (each pad is 0.4mm wide), but I'm thinking there may be people here who can build and use a board for their machine? Please let me know what you think of the guide, and if this is useful. Thanks, Andrew

I am trying to test a stock NTSC 600XL to see if it works. It does not have a monitor port. I don't have a TV with an antenna hookup on it. Any ideas as to how I can test this?

Well I figured this is probably the best place to ask. I got an atari 600xl a year and a bit ago, didn't come with a power supply and didn't get one till about 6 months ago. I got some cart games and software to play around with and when I was messing with the self-test, the RAM test kept going for a long time, up to 48 blocks of RAM were tested. Concerned that there was a bad RAM chip, I opened up the machine and discovered a massive Applied Engineering RAM daughter card installed over where the stock RAM would've been. I thought Applied Engineering only produced upgrades for the Apple II, Mac and Amiga machines? I looked up the data sheet for the RAM chip type on the board, and it turns out there's a bunch of 4K chips that add up to 64K total. Can someone shed some light and tell me what the hell have I got? An apple II upgrade that was modified for a 600XL, or an actual AE stock product sold for the 600XL? Will post pics later when I crack the machine open again.

Hi Everyone. Are there shrink-wrapped new hardware solutions on the market that do the job of a 600/800XL? And a 1050 disk drive? I have heaps of cartridges & 5.25" games which I can't use now as my 600XL & 1050 are both dead. I am not a hardware literate so I can't do maintenance on these. I was vaguely interested in the Brewing Academy's 1088XEL/XLD options, but they offer a heap of hardware options which I can't navigate. I also can't find in Australia any second-hand 600/800XLs for sale. Any help would be appreciated. cheers, Jonathan

Hello guys As most of us know, you need 64kB of main memory for most memory extensions. But some of us are reluctant to open up the 600XL to replace the two 16k RAM chips with two 64k RAM chips. And the 1064 are hard to come by sometimes. That's when the following idea popped into my mind: Would it be possible to design/realize a 1064 replacement, using modern hardware to make the device smaller, that could also be used with any external expansion that requires 64kB of main memory? With this redesigned 1064, the 600XL should look like an 800XL to all devices connected to it (via whatever port/bus) and should be able to handle every piece of hardware the 800XL can handle, without any restrictions the 800XL doesn't have. Sincerely Mathy PS as always, this is just an idea. If you like it, please realize it. I'm not able to. I just come up with the (dumb) ideas.

Hi All, I will be selling my collection, as a bundle. There are some gems in there. Atari Roots for one, Mac/65 with manual and big box Robotron. Also a spare NOS 400 keyboard, and an 800XL mobo. 2 USB power for XL series adapters and an XIO to USB. I am looking for reasonable offers. I live in the Los Angeles Area. Thank you. KB

Lately I have been finding new power supplies for XL and XEs on eBay that looked a lot like a 5 volt power supply with just a new 7 pin head. As anyone who has ever had an Atari XL knows the power supplies for the XL weren't all that reliable and even though the power supply I have for my 600XL was working I thought I would build another on using current technology like the ones I have been seeing on eBay and make the old one a spare. SO that is what I did and this is how I did it. Legal: I am not a professional but have had years of experience with computers. Still, use these instructions at your own peril. I assume no responsibility. Note: use this information only if you know what you are doing. Get the polarity wrong and you could BLOW YOUR COMPUTER. So always, check, check and check. The power supply plug on the XL line attaches by a 7 pin DIN plug. looking down at the plug the left 3 pins are negative and on the right 3 pins are positive. the bottom pin is nul and not connected to anything. But, on my 600XL, only 1 pin on each side need power. So the 2nd pin from top on left got negative and the 2nd from the top right got positive. All the other pins don't need to be powered even though the Atari power supply does power them. (I assume the 800XL is the same but since I have not tested one test, test, test. ) 7 pin DINS are hard to find and expensive. So, since only 1 pin on each side needs power I used a 5 pin DIN which is easier to find and cheaper and it fits. NOTE: It was pointed out that the monitor port ALSO uses a 5 pin on the 800XL which I had forgot about since the US 600XL only has a RF connector. IF you use a 5 PIN for power be sure NOT to plug the power into the monitor port by mistake. Bad things will happen if you do, very bad. Here are the specs for my power supply OUT is 5 volt, 2 amp. The Atari power supply was 1.5 amp so I wouldn't go any lower than that. The Actual 600XL draws 800mA but you might need the extra amps for SIO port devices (such as Fuqinet) that draw their power from the computer. Oh, and if you are wondering where the power supply came from it was an old power supply for a powered USB hub. Using an old USB powered hub I knew the power was steady and filtered. Using just an old phone charger might not work as well as it could introduce interference or power fluctuations. So check it out before you commit. Here is what the plug end looks like. Pin 2nd from top left is the negative, pin 2nd from top right is the positive. all other pins are un-powered. Here is the finished item. As I said before, test, test, test and double check yourself before you attach it to the Atari. If the polarity is wrong it could brick your computer. After I attached the power supply I ran a stress test of a little program and then the builtin Atari check program in a loop for quite a while. It held up fine.

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

Hi everyone, I'm a complete n00b and I'm looking for some advice. I've dusted off my old 600xl which was a hand-me-down from my uncle back in the late 80s and decided that it would be a great project to get it back working again. Upgrade it and show it to my uncle, who's now in his 60s. its a stock 600xl, PAL region, membrane (mylar I think) keyboard. I've created a twitter thread here documenting my progress to date: So far I've given things a general clean and retro-brightened the case and that of the 1010 cassette deck. I've checked the PSUs, 600xl is fine but the tape drive doesn't work. I've sourced one that will do the tape drive from my parts bin. Everything went back together fine, hooked it up to the TV, turned it on and very surprisingly got the "ready" prompt. Unfortunately the keyboard isn't working with the exception of reset, option, select, start, and break. Thinking it was membrane oxidation, I stripped the keyboard back down and used a magic sponge to clean all the traces. I was surprised at how well that worked! I also swapped around the 2x 4051 chips and reseated C012294-19 (POKEY, I think) to see if that would make a difference. Unfortunately not, same as before only the silver buttons & break work. Those keys were enough to get into the diagnostics; memory checked out ok but no sound over the antenna cable. So I'm looking for a bit of guidance on where to go next. Pokey dead? I can imagine they're hard to come by these days. Some googling lead me to something called POKEYMAX. Keeping in mind that I'd like to upgrade the memory too, what options do I have? Advice and guidance welcomed! Thanks T

How many mods has someone actually squeezed into a 600XL? I love the small size, but realistically I know there is limited real estate inside. It would be great to have everything: U1MB, VBXE, stereo pokey board, u-switch, TK-II or AKI, Rapidus, and I'd have to do the 64k and a/v mods. Is it doable or do I need to play it safe with a larger model?

Hi, I´ve a PAL 600XL for repair and was surprised about the fact, that only GTIA, ANTIC and CPU were in sockets - all other parts are directly soldered in! Until today I never have had an Atari 600XL seen with a mainboard, where NOT all chips are in sockets. Not dependent if it was a PAL or NTSC 600XL mainboard. I´ve made some pictures... (Both DRAMs, both 74LS158, the 74LS375 and 74LS32 were desoldered and sockets placed in by the owner - originally these chips were also directly soldered in) Also not common: Basic "C" - I never found a Basic-C version in an Atari 600XL. Datecode "1284" is very late for 600XL...? Also I never saw such "rubberfoam" at the PBI´s connector (bottom, solder side). Any comments? BR Jurgen

So I want to get data tapes for my 600XL, but XC12 tape recorders are easily over $100! I'm a total cheapskate, so I was wondering if there's any chance of an alternative. Will a plain old audio cassette player do if I have the right hookups for it? And if not, what are some cheaper alternatives?

Hi all, I've been looking for this information all day yesterday, but could not find a specific answer to my question... I have a stock 600XL (16Kb of memory) and I wanted to test my SIO2SD on it yesterday, but could never get to the screen to select the game or software I wanted to launch. I was thinkng I did sometime wrong and the SIO2SD was not properly configured. But I tested it on my 800XL, and it worked right away. So the questions I have are the following: 1) I guess it is because it does not have enough memory and BASIC is going over/before the SIO2SD software can load. Does this make sense? 2) is there a way to tell it not to load BASIC and load the SIO2SD software first? 3) I read that 16Kb of memory may not be enough for most games, is the only solution to use a 600XL is to upgrade it to 64 Kb? Thank you all

I have an Atari 800XL PAL unit with Supervideo XL mod that I paid a good bit for from Germany. The keyboard in it had a stuck key. I confirmed it was mechanical. Air did not help so I took the membrane loose. Apparently a mistake. Replacing after cleaning, only the function keys work. Reseated cable repeatedly. I was going to buy another unit on eBay and take the keyboard, but they are too expensive, so I will not be watching scene demos on this but shelving it, it seems. I can't afford a new one. (Someone is currently selling a PIECE OF FOAM from the box of a 600XL for $32....) Before I close the door on my A8 experience for probably a decade, I wanted to see if anyone had a spare keyboard for the unit that I could buy for a fairly low price. Probably not, but I wanted to take one more chance before I put this broken system away. Thanks. :-/ bp

I've been having a weird SIO problem that I'm hoping someone might have some insight into. The symptom of the problem is this. The Atari will attempt to read a sector (or some other SIO operation). There is about a 70% chance that it will succeed, but the other 30% it will sit for the timeout period (a few seconds) and then retry the sector read. I've seen a sector fail to read 3-4 times in a row before it succeeds and then a bunch will succeed in a row. The aspeqt log looks like this: [Disk 1] Get status. [Disk 1] Read sector 1 (128 bytes). [Disk 1] Read sector 2 (128 bytes). [Disk 1] Read sector 3 (128 bytes). [Disk 1] Read sector 4 (128 bytes). [Disk 1] Read sector 5 (128 bytes). [Disk 1] Read sector 6 (128 bytes). [Disk 1] Read sector 7 (128 bytes). [Disk 1] Read sector 8 (128 bytes). [Disk 1] Read sector 9 (128 bytes). [Disk 1] Read sector 10 (128 bytes). [Disk 1] Read sector 11 (128 bytes). [Disk 1] Read sector 12 (128 bytes). [Disk 1] Read sector 13 (128 bytes). [Disk 1] Read sector 14 (128 bytes). <-- this is the failed command [Disk 1] Read sector 14 (128 bytes). [Disk 1] Read sector 15 (128 bytes). ...etc... So aspeqt isn't noticing a problem; rather the system just isn't seeing the sector come in for some reason. Here's the history of the problem. It all started when I dropped in a PAL ANTIC for playing some PAL games. At the time I figured the occasional glitch might be due to timing differences so I didn't think anything of it. After a few weeks of not using my system, I received and installed one of mega-hz's stereo boards (in the process I moved my OS ROM IC to the BASIC spot and removed BASIC, because in a 600XL the board doesn't quite fit). I booted up and everything seemed to work great on the first try, *except* that this SIO problem was still there and in fact was quite a bit worse than it was before! Figuring I had banjaxed something (SIO = POKEY = seems like it might have been related to the stereo board install), I tried reverting the upgrade and there was no change - the SIO problem was definitely still there. I swapped my ANTIC out for the original NTSC one again hoping that this would resolve the issue but it did not. I checked and rechecked the board for broken traces along every path I could find, even tried different POKEYs to no avail. Then I made a quite interesting discovery. If I boot in Aspeqt using the "boot XEX" feature, it consistently works fine (after it loads the initial few sectors containing the boot loader). This is interesting to me because the OS loads sectors at 19200 bps, but the Aspeqt XEX booter uses 57600 bps (I believe) to transmit the XEX data. So maybe the problem is actually in the OS ROM somehow, though I don't see how since it passes self-test which I think does a checksum test. My other thought is that maybe IRQs are not being handled right somehow since (I think) the OS SIO routine is IRQ-driven, whereas high-speed boot loaders aren't? Anyone have any thoughts about what I should try next? I was thinking about writing a test program pair for the atari and linux which transmits a data stream and checks for problems, and maybe just swapping ICs (SALLY gets a little warm but I think that's her normal behavior).

Hi all, I've got a problem with a 600XL and I'm not sure how to solve it. When the machine is started up it immediately goes into the memory test and the 2nd ROM test is red as shown in the screen shot. Here's the things I've done: Swap GTIA with 800XL and chip works fine. Swap ANTIC and things work. Swap Pokey and things work. Swap Sally and things work fine. Swap PIA and things work fine. Swap BASIC ROM and things work fine. Swapped OS ROM and the 800XL had a black screen. Performed the composite mod from Best Electronics. Ordered new CO61598B from Best Electronics. The new CO61598B is giving the memory test failure. I did the composite mod to the 5-pin din and after the mod was done it booted to the Ready screen once, then the memory test failure each time after that. I've tried the new CO61598B in the 800XL and it does the same thing. I haven't tried the CO61598B from the 800XL in the 600XL because I'm afraid that something in the 600XL is blowing out the chip. Is there anything I can check to make sure that there isn't something in the 600XL causing the problem with the OS ROM? Thanks for your help, I appreciate you reading through this long post.

Just what it says on the tin, folks. I've got a pretty sweet, never-used 600XL sitting in a box begging to be modded. I know it's a simple mod in terms of the actual work required on the machine - just wondering what types of DRAMs I need to track down. Thanks for any pointers in the right direction.
