Originally posted on FB... After putting it off for a few years, I finally made a nice looking VGA port for the TI99. Here is my design. I haven't yet tested it on a black console yet, but I am sending it out to a few people to try. It requires you to remove the original AV port and solder your audio wires to the board. And it also requires you to cut a rectangular hole on your console shell 60x16mm. More details to come. Darryl

While trying my cartridge-to-breadboard adapter, I got this screen upon startup: What does it mean? The F18A is an original from 2012, not upgraded, in a silver-and-black console. When I unplugged the adapter the computer started normally. My adapter is this. I was using one of those fancy 80-pin IDE cables to connect to a couple of logic gates on the breadboard. K-R.

Here's a thing I've been playing with, and thought about putting it in a separate thread. With the help of @Asmusr I tweaked the f18a emulation in my local clone of js99er, so that it can now run in 60 rows, 80 columns mode. The idea was to see how I need to setup VDP memory to get stevie running in 60 rows, 80 columns mode and do refactoring for the different video modes (24x80, 30x80, 60x80, ...) This is still a work-in-progress and will never be officially released, but it does prove that it's doable. As a starting point I took the stevie build I made for classic99 where I use a character cursor instead of a sprite cursor. (Sprite cursor is possible, but will only get halfway the screen, due to 1-byte for Y in the sprite attribute table, so of no real use here) Anyway, the build for classic99 was also a hack, because I refresh the frame buffer each time the cursor blinks. That clearly shows here, because I'm dumping quite a bit of data to the VDP and it gets a bit slow. So, next thing to do for me is to get that cursor routine a bit smarter. You never know, maybe the f18a mk2 will support a 60x80 mode. I'm still wondering if it'd be doable on the f18a mk1 with a firmware update, but I think Matthew said it won't work because of VHDL already being chuck-full. 16K of VDP memory is enough though, as my demo shows. Enjoy the demo (VDP corruption at the end when turning on the ruler., but that's part of the fun. I still need to fix some things in stevie). js99er-20230123204409.webm

I have found a supplier that can provide the required Xilinx IC to manufacture the original F18A (VGA Connector). I have ordered a handful of chips to verify, and they are good. These chips have skyrocketed in price over the last couple of years. If you are interested in purchasing a VGA version of the F18A, please go to my link at the bottom of this post to submit an interest. With the price of the chips be aware that the price of the unit will be between $150 - $175 USD. This is dependent on how many I order at one time. Interest form: https://forms.gle/2MQAH79SUqqCuQGz5 The F18A has been installed in the following systems: TI-99/4A Home Computer ColecoVison Game Console (1) ColecoVision ADAM Computer (1) Toshiba HX-10 MSX1 Computer Toshiba Pasopia-IQ MSX1 Computer JVC Victor HC-7 MSX1 Computer Yamaha CX5M MSX1 Computer SpectraVideo 328 Computer (1) Tomy Tutor (1) SEGA SG-1000 (2) SEGA SC-1000II (replaced a TMS9118 VDP) Telegames Personal Arcade Powertran Cortex Memotech 500 and 512 (2) Features with latest firmware (1.9): 80-column (T80) mode. Position-based attributes for T80 mode, so each tile can have its own foreground and background color. 64 programmable 12-bit (4096) color palette registers. High-speed “data port mode” for fast palette register updating. Three enhanced color modes (ECM) that provide 1, 2, or 3 bits-per-pixel allowing 2, 4, or 8 colors per-pixel for each tile and sprite. 32-sprites on a line at once (can eliminate sprite flicker if software did not implement sprite-rotation). Each sprite can have its own size (8x8 or 16x16), and X/Y pattern flip. 30-column mode that provides 32x30 tiles (same as the NES). Two independent tile-layers, each with their own name, color, and pattern table base addresses. Per-tile attributes so each tile can have its own foreground and background color, priority over sprites, X/Y pattern flip, and transparency. Independent horizontal and vertical pixel-scrolling for each tile layer. Tile page sizes of 1x1, 2x1, 1x2, and 2x2 to support edge-to-edge pixel scrolling. Bitmap layer with programmable size from 1x1 to 256x192 pixels, pixel locatable, 4-colors per pixel, 16-colors per pixel “fat pixel” mode, sprite priority, and palette select. Programmable horizontal-line interrupt. Programmable signed increment value for the VDP Address Register. Ability to read all VDP Registers. Programmable 46-bit decimal counter with 10ns (nanosecond) precision (can count 18.2044 hours with 10ns accuracy). A 100MHz TMS9900-based “GPU” processor that can execute programs in VRAM, has full access to all VDP Registers, a high-speed DMA, and dedicated pixel-plotting and address instructions. Virtual scan-lines for a retro CRT look. VGA 640x480 60Hz video output. If you are interested in

Would it be possible to access (read and write) the original 16K VDP memory RAM from the F18a GPU? Guess not, at least not for writing. But asking anyway, you never know. Would be a cool for a future F18a firmware revision to access the 16K VDP memory on the main board as a second bank of VDP memory.

I read the documentation and looked at the register excel file, but questions remains (and I'm assuming I'm doing something wrong in Stevie) What is the proper way to halt the emulated TMS9900 CPU in the F18a? Is it sufficient to use the IDLE instruction as last line in assembly program or do I need to halt the CPU in the F18a GPU by writing 0 to extended register VR56 (>38) ? What is the proper way to lock the F18a GPU after it has been unlocked? Is it sufficient to write >00 to extended register VR57 (>39)?

SOLD For Sale: Quantity 2 (F18A + VGA header set). LIMIT one + header each to two separate buyers to spread the wealth. CONUS shipping only. Boards new, still sealed in their anti-static bags (original receipt pic below to prove I'm original purchaser and V1.8 firmware). Not TI-99/4A-specific, but they do have the low profile pins. I never got around to opening them and installing into a console to update to V1.9 (latest version). History: I have been running three others purchased in the same 2017 frame in TI-99/4A computers with zero issues or had to return one for repair or due to DOA! No warranty or support; selling as is. Specific install application and any firmware updates fall to the buyer. I will photocopy the fact/install sheet so each buyer gets a copy. With the MK2 due out soon, I'm asking $65 ($57 each + $8 postage via USPS insured small flat-rate box). Sorry, that's what I have on hand due to the COVID-19 environment. Just trying to recover some on a previous investment to be able to afford new, future TI-99/4A gadgets. ? As this is my first listing here I'm going to keep it simple (for me) by asking payment via Paypal "friends and family" with verified address, subject to terms above and replies HERE to keep it above board as I'm not playing PM race the clock. First come; first serve ... then we can hash out details via PM with settled payment to hopefully get them out to y'all this week. Thanks in advance for your interest. Doug

I noticed in the F18a spreadsheet that there's a high-resolution timer in the F18a. At least that is what the F18a Status Registers SR3-SR11 indicate. Is my assumption correct? Did anyone use this timer yet?

I will be using this thread to document the development of a new programmer editor for the TI-99/4a called "Stevie". Download the cartridge image in the official release thread. As you might expect from its name, the editor is somewhat inspired by the unix editor "vi" and will also take elements of "tmux". So what do I have in mind: Designed from the ground up for 80 columns mode, specifically using the F18A but 9938 will be supported as well. Designed from the ground up for using SAMS card. Programming language of choice is TMS9900 assembly language The editor itself will run from cartridge space (multi-bank cartridge). Uses my spectra2 library as foundation (been doing major changes in the last couple of months, not related to games) Will have some "API" so that I can integrate with external programs and go back and forth between programs. Would like to add some kind of mouse support. This will not be a GUI in the traditional sense. If you used tmux with a mouse before you know what I mean. Possibility to have multiple editor panes open at once. Should handle files with up to 65536 lines Undo functionality, well up to a certain extent that is. Language awareness, e.g. behave differently based upon language (e.g. assembly, C, Basic, ...) Internal text representation will be decoupled from what actually will be rendered on screen. Should make the editor more responsive when dealing with large files, allow split panes, etc. Reconfigurable keymaps, possibility to swap between keymap with single key combination. Not everyone is into VI This is the start of a large project and I don't expect to have a truely useful version anytime soon. I expect this project to take multiple years, but you gotta start somewhere. Now I've taken my mouth full, I will use this thread to keep myself motivated ?

Think I read somewhere that the F18A also supports a 30 rows/80 character mode as opposed to the "normal" 24 x 80 columns mode. If that is true, can someone point me how the F18A VDP registers must be set to activate the mode? Thanks retroclouds *EDIT* It's 30 rows, not 31 rows.

HELP! I've been working on this project: http://github.com/calphool/TRS80GS I've built 4 revisions of this board for my friend's TRS-80. I've had a heck of a time keeping the VDP chip working in a stable configuration. I had everything working for a while, and then suddenly it decided that it wouldn't work any more. I screwed around with the caps on the crystal (soldering on heavier leads and stuff), and eventually it blinked back to life, but now I only have a luminance signal (or at least the TV can't interpret the color part of the NTSC signal, so I get black-and-white). What I need is a very stable clock, and unfortunately there seem to be about a half dozen different examples of how people have set up the clock on this chip. Here are a few: I need something that just always works, not something that's flaky and subject to weird transient noise. The VDP and its clock divider are basically the heart of my board now, and if I can't get the clock working right, nothing works (the sound chips and UART chip use the divided clock signal that comes out of the VDP for their own clocks). What's the best way to make sure this clock is super stable and reliable? The Texas Instruments hardware design? It's got a bunch of stuff inline (including something it calls an "SR Inductor" that has no uH rating, and I'm a little confused by). The ChromaTRS design? It's got some inverter gates attached to the crystal (though it doesn't specify the value for the resistor it's using). I've been using variations on each revision, with the most recent being the one from Byte magazine, which is flaky as all get out.

I normally don't like to announce things before they are ready, but I can't keep making excuses to those waiting and asking about the next F18A board run. For the last 6 months, while requests for the F18A were trickling in, I have been working on a new version of the F18A, called the MK2, to solve the problems of the current board. At the point were I had enough requests for F18A boards, I was not quite ready with the new MK2 design, so I continued to avoid the direct question of "when do you think the next F18A run will be?" To not have to keep making excuses, and with apologizes to those who have been waiting patiently for a long time, I'm announcing the F18A MK2 now, about a month before it will probably be shipping. I wanted to do this so people would have some real status, and to help my conscience (Vorticon, I spelled it right this time... ). Here is a link to the long version of the story: http://codehackcreate.com/archives/592 I'll do the short and sweet version here. The primary features of the F18A MK2 are: * It is 52mm x 19mm, i.e. the same size as a standard 600-mil 40-pin DIP socket, so no tall-pins, short-pins, adapters, etc. will be necessary for it to fit in the host computers. * Digital video output (TBD, probably DisplayPort). No, there is no VGA, sorry. See my post above for the details on that. Digital video to VGA converters are available if you really need/want VGA. * Host audio injection into the video signal for those who can manage to connect one wire internally to pick up the system's audio and get it to a pin on the MK2. The MK2 will run the same core as the original F18A, and I am still committed to supporting, working on, and fixing the original F18A issues (there is a known problem with the interrupt on some systems, etc.) Future features based on the enhanced MK2 hardware. Access to these features will come with future firmware releases (I don't have time to do it all at once, sorry): * The MK2 has 512KiB of 10ns SRAM, i.e. basically 512KiB of VRAM. This VRAM will be available in a 9938-compatible way, and then some. * The MK2 has extra I/O, including the Mode-1 pin to make it possible to do the 9938-update to the 99/4A in a "TIM" manner. * More than double the FPGA resources than the original F18A. This means more possibilities for new stuff in the VDP. Other non-TI related possibilities: * With simple low-cost adapter boards to re-arrange the wiring, plus a firmware change, the MK2 can be used to replace other VDPs like those in the NES, the Master System, MSX2 (i.e. 9938/59 system), etc. * Stand-alone FPGA-based game system due to the on-board 9900 CPU and 14 extra general-purpose IO pins. * General purpose FPGA devboard. * More simple SPI-based host interface to use the MK2 as a video chip for simple micorcontroller projects, i.e. Arduino, etc. I plan to keep this thread updated with status and to gauge feedback. If all goes well, and if I have not just made a big mistake, I hope to have the MK2 shipping by late July. Ironically this will be exactly 6-years after the original F18A shipped!

A few years ago I was playing around with the Infocom Interpreter, trying to make it compatible with the F18A 80 column mode. In the original 80 column interpreter, the pattern descriptor table was relocated to VRAM bank #1, something that only exists with a V9938 configuration. The attached disk contains a version of the interpreter (ZORKF18A) modified to work within the constraints of the original 16K of VRAM. I have tested the program with both Classic99 and js99er. I do not currently have my F18A system up and running, so it would be helpful if someone would give this a whirl on the real hardware. Thanks to Shift838 for his help gathering the missing details to make this possible. If successful, I will update the other interpreter(s) that are needed for the ported games. (The game files have been validated using the $VERIFY command) ZORK1.dsk

Could someone please try the attached binary on the real deal? It's an 8k cartridge ROM that runs on the unexpanded console. I've been working on enhancing my spectra2 library with some new routines and would like to check if the Hardware is recognized in a reliable way. It should test the below: 1. Check if F18A is installed 2. Check if speech synthesizer is available 3. List the VDP refresh rate 50/60Hz Thanks. test1c.bin

I spent much of the weekend opening my 99/4A, removing the cassette jack, installing F18a, placing VGA out in the place of the cassette jack, etc. Powered on and all was good. Fun last night and was online (telnet BBS) via WiFi232 and TIMXT this morning. Left the term prog loaded all day while I cleaned and rearranged the room so I can actually sit in front of the 99 to BBS properly, aaaand.... I noticed the text on TIMXT was no longer white but a muddy color. No keyboard response. I powered off and on -- no more video output. I can hear the TV power up, I hit 2 for FR99, can hear things as I navigate thru it and load a random cart and I see from its LED that it's loading a cart. But no video out. I tried it on a different VGA LCD, no video there either -- so it's not my screen. SO disappointing. Was so looking forward to BBSing in ANSI color on the TI here on my 45th birthday (today). Definite birthday downer. I really don't want to pull everything out again and open up the TI -- no energy for that again, not tonite. Any ideas out there? Is there a chance things are not fried? I now the TI needs the gfx chip to access memory, or I believe it does. So, it can't be fully fried. The ribbon cable is well secured, screwed into the case. No stress on it since I turned on this morning. https://twitter.com/blakespot/status/866030731725819904 Thanks. bp

I've got two TIs with the same ailment. Black screen on power on with the unending tone. Both occurred in relation to an F18A mod (but I would guess the F18A is not the cause) and I was wondering if anyone had some brilliant advice that could save the day, or advice in avoiding future tragedy. Story Time - Not for the faint of heart, you have been warned. Beginning this year I got the urge to start playing with my TI-99/4A again, my TI had been sitting idle and collecting dust for a few years ever since it's TV went away. It was a stock TI, no expansions apart from the speech; and I was really interested in improving it to explore the community offerings. I read about this fabulous modification called the F18A that completely overhauled the TI's video out. It didn't seem too difficult, so I ordered one as soon as they came available and waited patiently. After a time I received the magic F18A and dutifully opened my TI, removed the VDP, and installed the F18A. I then dremeled some holes for the VGA cable and snaked it to the back of my console. Shield, attach, close up, power on, total victory! Everything seemed to work without complaint and I was playing Tunnels of Doom on my computer monitor the same evening. What followed were some good times, a month or so of vintage happiness. It was not to last. A few weeks ago I powered on my TI so I could continue one of my latest Quests for the King. Black screen, blaring tone. As near as I can tell this was a spontaneous failure as nothing had changed - the system hadn't been opened since the F18A and it had powered on fine the evening before; no new expansions or cable changes. The internet informed me this dreaded error could mean virtually anything wrong with the system. I opened the system and did the only diagnostic steps I could handle. I replaced the original VDP and tried to power on. Nothing. Tried putting the F18A back and powering on. Nothing. I started re-seating the GROMs and clock chip. As I gently pried and lifted the first GROM it suddenly flipped 180 and attacked me, impaling my poor finger. I quickly deduced the reason, I had snapped off two of the pins. Disaster. Nonetheless, I carried on to see if any change in the system state could be discerned from the re-seating. The TI was unmoved by my efforts and continued with the black screen and harsh tone. As I was working with the TI motherboard, and under unremembered circumstances. I took hold of the keyboard ribbon cable to attach to the motherboard and instead had it come away in my fingers. Catastrophe. The keyboard ribbon cable had sheared off from the solder points on the keyboard. I sadly realized that my efforts had probably already killed my patient, I honestly am not equipped or knowledgeable enough for computer surgery, and should no longer indulge in this pointless torture. I resolved to visit eBay and order another TI. A scan of ebay revealed that TIs generally would cost $50 after shipping. I decided to go ahead and order a lot of 2 that were both claimed to be working but were missing some accessories (only 1 power supply and no RF) and one was missing keycaps. I bid, I won, and I waited. Yesterday the TIs have arrived. I verified that they were indeed functional as stock units (although the busted keycap one seemed to have some video issues). I set about opening the better of the pair to transplant my F18A. Unscrew, open, unshield, pry. Everything proceeding smoothly I gently pried up the F18A from it's old host and I let out a cry of genuine anguish. One of the pins was gone (nothing else bent or damaged that I saw, just cruel fate), the F18A had been wounded in this latest action. What follows is my descent into pure madness and unmitigated stupidity. Faced with the missing pin, and desiring to install the F18A in the fresh patient IMMEDIATELY, I resolved to solder a replacement pin to the F18A board. Now some background, in years past some fool gifted me a inexpensive soldering iron as they knew my interest in vintage computing and thought I would find the tool useful. This tool would become a murder (of my poor TI) weapon. I have no training or formal education, and my past successful efforts with the tool have been only to solder wires together. A pin isn't that much different from a wire though? Of course not. So I cut a pin from a bit of discarded electronics I had laying around and proceeded to attempt to solder it to the board. What followed was an hour of trembling hands, cursing, fiddling, and jabbing a hot iron at the little board to try and get the pin to stick and not be crooked. Each passable attempt ended in failure, resulting in a black screen (but accompanied by the TI's lovely startup chirp). These efforts were interspersed with periodic sanity checks with the original VDP which I would insert to verify that I had not inflicted fatal injury. This continued until finally a measure of success. Video, but not that which brings joy, but a hideous abomination that shrivels the soul. The system powered on, but showed a title screen that was corrupted. The colors were wrong, the characters were garbled. Further desperate action improved nothing: from garbled screen, to blank blue screen, to black screen, to F18A ready screen, to garbled screen; round and round till I resolved myself and admitted defeat. However, the drama still had one final cruel twist of fate. I placed another F18A order and replaced the original VDP. Only this time instead of the grainy title screen I was greeted by doom's horrible screech. Black screen, blaring tone. Panic. I tried replacing the F18A. Black screen, blaring tone. Re-seat all the socketed chips. Black screen, blaring tone. Swap power supplies. Black screen, blaring tone. To my shame it seems I have killed another patient. Now I confess my eyes have shifted to my last misshapen TI to perhaps harvest its organs to fuel my mad designs. One potential slight glimmer of growth, I have decided to err on the side of wisdom and solicit my betters, and prevail upon their wisdom to see if there is any way I may undo this horror, or at least advice that I may prevent another one. Well? What say you? TL;DR - I am an idiot. Due to botched install+repair I'm soliciting help/advice in fixing my TIs. Black screens, blaring tones.

As mentioned elsewhere, I've been building a collection of F18A / slideshow99 compatible pix using Tursi's little convertor proggy (which is a lot of fun to fiddle with). And so here's a small batch.... I was going to categorize them, but I'm way too lazy to be that organized. That being said, I have created a separate disk of NLL (National Lacrosse League) logos (past and present) since, as always, I become completely obsessed/stressed-out at this time of year as the post-season draws ever closer... I know, I know, what kind of Canadian puts ANYTHING above hockey??? Well, I was raised in a Lacrosse town, so I like my hockey to have BALLS! (Although congrats to the Leafs for making it into the Playoffs). I've attached a single ZIP file for those who do not use a CF7/nanoPEB, so that you can use HDX, Floppies or your storage medium of choice. If you do use CF's I have also attached 5 separate CF7 discs (each contains 21 images). All but two or three of the images are converted from bitmaps I have on my PC, so many will be instantly familiar, but I think it's safe to say, this is their first appearance on a 4A. If there is already a thread where we are sharing these (besides the sample batch in the Flashrom99 thread), I ask that these get moved there and point me there for future reference. But if this is the first such post of this kind, then what's up with that??? I haven't looked, but I'd wager there are forum repositories of Spectrum512 images in the Atari forums!

OK, so I just installed an f18a on my ADAM a couple of days ago and it worked great...until I put my ADAM back together today and now when I turn it on I get this screen. Any ideas? I'm not looking forward to tearing the thing apart again!!!
-
I got my F18A a little while ago and I've been waiting for some free time to get it installed and try it out, but I figured I'd ask the forum if anyone has any particular tips or best practices for mounting and installation. Any particular VGA bracket mounting location better than others, best way to modify the case, etc?
-
The F18A is back in stock for anyone who was waiting on one. Please note that it might take me 4 to 5 days to fulfill orders and get them shipped, so please be patient if you order one. Thanks! http://codehackcreate.com/store
