Hi all, Thought I'd share a project I've been working on. I recently bought a beige '99 which had the infamous Mitsumi mylar keyboard which wasn't working at all. :( I did manage to sort it out to work *relatively* well, but in the meantime, decided (with some prompting from Derek Christenson) to design a replacement keyboard which uses modern (Cherry MX compatible) switches. Additionally, it uses the original Mitsumi TI-99/4A keycaps (via 3D printed adapters) for that original look. I've tested my first revision (v0.1) board and it's working great. A couple of minor adjustments for v1.0 and then I'll release all the details for general consumption. The project could be adapted to use new (or perhaps other keyboard types) keycaps at a later time, but I created it for the very specific use-case of upgrading a Mitsumi board. If you'd like to follow the project: Hackaday: KEYBOARD/4A-99 | Hackaday.io GitHub: visrealm/keyboard4a99: Modern keyboard replacement for a Texas Instruments TI-99/4A (github.com)

A month ago I posted on this forum that I was selling some Atari 800 mechanical keyboards. I now have a few more available: The keyboard is a drop-in replacement, already includes all of the required 3D printed parts all you need is a screwdriver (and your Atari 800 keycaps). I'm asking $65 (USD) + shipping (from Cleveland). I put together some installation instructions (although installation is fairly straight forward) and there's some photos in that PDF if you want to check it out. After my previous posting 3 people PM'd me about this and two have purchased, one said he wanted one but so far has not yet responded from my email. So I have 2 available for sure and possibly another 3rd if that person doesn't respond in a few days.

My console has a "JediMatt" USB keyboard adapter that I bought from (I think) arcadeshopper. The adapter does not recognize the keys F and U (both upper and lower case), +, =, or the left-shift key. The right-shift key works as expected. Anyone have this problem? K-R.

The DecentXL replacement keyboard for Atari 600XL and 800XL, winner of the 2023 ABBUC hardware contest, is now available in its modern version (all new keyboard, including key caps and console keys) for $299 + shipping ($15 to the US) & tax (depends on the state). It's also available as a kit for $240 + shipping & taxes. (photo is of my prototype, production models may vary) Check out all the technical details on the GitHub page: https://github.com/bleroy/3d-junkyard/blob/main/DecentXL/readme.md As with all my designs, this is 100% open-source hardware (you can make your own). The keyboards are made to order, so expect 2-3 weeks before it ships, depending on my part inventory. To buy, send me a PM with your choice of switch (clicky, tactile, linear, or your choice of brand and type) and your payment at https://buy.stripe.com/00gbMm0dXceIg804gg. Note that it's considerably more expensive for me to send keyboards outside of the US: you are likely to get hit hard by tariffs in addition to expensive shipping. A note on vintage keyboards, that adapt the original Atari key caps on top of modern low-profile switches: these will be available at a later date and only as kits. The first supported key types will be Stackpoles (square) and Alps. UPDATED 3/23/2024: prices lowered after the design has been simplified.

Hi. I want to use the Adam keyboard from a Colecovision cartrigde, it should be possible but not easy I guess, any one have some sample code ? -
Hello there, I've found a lot of 20 TI99 keyboards on my house (are new with plastic envelope). Just checking if anybody are interested on getting one (or all). The keyboard can be used on a normal PC with a Teensy 3.1, and I think the keycaps could be used on Topre keyboards. Please note that I'm on México City, so the shipping could be expensive for the entire box, but selling one by one could be a better choice. $30 per piece or $500 for all (plus shipping and PayPal fees)

Atari 400 Keyboard - Shift, Ctrl, Break not working.
slacker posted a topic in Atari 8-Bit Computers
Hi All, I've been working on fixing up an Atari 400 my friend gave me. It started with just getting a BSOD at boot. After attempting to clean and re-seat all the chips on the main board, CPU board, and RAM board with no luck, I picked up a 48k RAM upgrade board. After installing that, the computer booted! All keys on the keyboard worked and was able to use my BASIC cart for a while without any issues. I then I ran into another problem then where the joystick ports didn't work. (Just to note, these didn't work from the start, they didn't stop working after the computer booted for the first time) I was able to get those working by installing a new PIA chip (G65SC21P-2). Things seemed to be fine at this point. I played some games but then had issues with keyboard suddenly missing keys. Surprisingly, pulling and re-seating the PIA chip fixed this even though I was under the impression the keyboard was controlled by the POKEY and the two multiplexer chips. Anyway, long story short, I'm at the point where everything works great except the SHIFT, CTRL, and BREAK keys. These used to work as I was able to program a bit in BASIC earlier but now they're suddenly not working. I should also note, I have a 5200 that I swapped the CPU, GTIA, ANTIC, and POKEY chip back and forth into the 400 and it didn't make any difference to anything. I also swapped around the two keyboard multiplexer chips without any change. I'm wondering if anyone has any ideas or if you guys know what pins I can jump on the keyboard connector to simulate pressing "SHIFT+2" to get a double quote or something. I've been able to jump some pins to get it to display a bunch of characters but I'm not sure what combo is needed to simulate pressing SHIFT. The pinout images I've found online don't seem to match up what I'm seeing on my computer. Basically, I'm trying to rule out if somehow I borked the keyboard taking things apart 1 million times or if some other trace, chip pin, or something is broke or making a bad connection on the main board. Thanks in advance! -
[UPDATE SOLD the 4 NOS 400 keyboards I had - still have one known good used one] For Sale: I have a small number of NOS (new old stock) original Atari 400 keyboards (the original flat ones). Please PM me if you need one. U.S. based. $25 + shipping. I have not tested each one however I used one in my tricked-out ‘keeper’ 400 and it works great. I also have 1 used known working 400 keyboard. $10 + shipping. They are lite but shipping takes a somewhat bulky box to properly protect the connector cable. I also have many Atari 8bit books and some cartridges for sale too if you want to combine and save on shipping. I will add links to my other FS items. Thanks for looking. 😁

I'm using ErgodoxEZ keyboard connected via usb and every time when I try typing something in the emulator (basic), my characters are getting lost in terms of that I need to press key multiple times to get a character on the screen. Is this a known issue or it's just my emulator config which is not tuned well enough to handle usb keyboards ? I'd appreciate if someone would post config here which is actually working to emulate 800xl. thanks !

Hello, I've recently been rebuilding my Coleco ADAM setup, most of which was sold off decades ago. Now I have a fully classic working system and a newly built ADAM drive emulator (ADE). All seems well, but I've been informed that I should be able to daisy chain the keyboard off the OUTPUT jack from a physical disk drive. When attempting this I get no light or function on the keyboard, although this keyboard (and another spare keyboard) work just fine when connected directly to the front or side ADAMNet jacks. Is there something I am doing wrong? I can successfully chain 2 physical disk drives without problem, but was advised to get keyboard chained before moving on to ADE coexistence with physical drive. Thanks for your advice, Shawn -
Where does the name "Keypad" come from? I only find it as "Keyboard"? There is the compatible "Video Touch Pad", maybe that names got mixed?

I managed to get the atari 800 I had when I was a kid from my mother's house, after she passed away. It had a bad space bar from way back, and my little brother mangled the little metal fingers under the key trying to fix it. Long story short, I replaced the keyboard with a new one. It worked great for about 10 minutes, then suddenly no keys are working. Putting the old keyboard back in didn't clear up the problem, so I have to assume it's something on the motherboard. After doing a bit of research, it seems like the Antic chip might be the issue, as absolutely none of the keys work, but I don't know how to diagnose it for sure. Further, even if I decided to buy one of those fast disappearing chips to replace it with, what caused it to go out in the first place? It seems rather coincidental that it goes out 10 minutes after replacing the keyboard, after surviving for 30 years with a broken space bar, and a year of use since I got it back, using it with the broken space bar. I'd like some ideas on what to test to maybe figure out why it would have gone out. I appreciate any help someone can give me.

What Midi keyboards are you using with your ST's? What is a good beginner one (49 key min) that won't break the bank? Wade

My girlfriend introduced me to her TI-99/4A from when she was a kid, it has been stored in her family's garage since the mid 1980's. We took it back to our house, plugged it in, and I've fallen in love with this computer. I purchased a FlashROM99, a TiPi, and a sidecar 32K expansion. The only thing I have found that is not functioning correctly with the computer is that instead of only Function + 9 resetting the computer, the keys 6,7,8,9,0 reset the computer, regardless of any other key being pressed / alpha lock on or off, joystick connected or disconnected. I have run memory test and all banks show OK. I tested the voltage from the external and internal power supply with a multimeter and all seems to be normal there. To rule out the keyboard, I disconnected the keyboard and when shorting the appropriate pins for numbers 6,7,8,9,0 the same reset behavior persists. Interestingly enough, when first powering on the computer if it's been sitting, and I open up TI BASIC, I can get those numbers to show up briefly when pressed, though a lot of other garbage (letters and numbers not pressed) appears and then the reset behavior reemerges and stays. I would be tempted to ignore this problem, however it is necessary to use parentheses in order to call on certain devices and functions when using the TIPI, and any press of the 8 key will reset the computer. I have read other posts regarding the TMS9901 being a problem for some, but when searching I can't seem to find any similar behaviors described that prompted their replacement. Has anyone else seen anything quite like this? I don't see any obvious signs of corrosion or leaking / bulging capacitors. I have replacement capacitors and TMS9901s (eBay seller recommended in these forums!) just in case but I wanted to see if anyone has any suggestions before I start replacing parts just in case it's a common problem and I can focus on the right spot first.

Hi everyone, A little while ago I was able to get an Atari 800 that was in pretty great condition with the exception of a needed cleaning. I decided that I wanted to make a custom keyboard using the original Atari's keyboard with the same switches and PCB. After taking the whole thing apart and separating the keyboard portion I learned the PCB was a Mitsumi KSD hybrid (ksd-a58au). I now don't know where to go because I was unable to find a complete Matrix or a new modernized PCB replacement. I also don't know what to do if I find a matrix as setting up a micro controller to interpret the and transfer it to usb sounded too complex for me. I was wondering where I should go from here. If anyone is able to provide useful information like a matrix or some idea as to how to make the PCB usb compatible it would be very appreciated. Thank you!

I just acquired a TI-99/4a system and all seems well, except that the majority of the keys don't work, or don't work every time. Turns out that this beige TI-99 has a Mitsumi keyboard. I'm going to try and repair the mylar. Any suggestions? It pretty much seems like a lost cause as the mylar is "stuck" to the pc board. Are there replacement keyboards for these machines to be had anywhere?

how much is the keyboard worth nowadays?

What is the worth of an intellivision computer/keyboard ? A 2600 sits on top of it.

MAME 0.226 You know what day it is? It’s MAME 0.226 day! A lot has happened in this development cycle, and plenty of it is worth getting excited about! First of all, there’s a change that affects all systems with keyboard inputs, including most computers. MAME now allows you to activate and deactivate keyboard and keypad inputs per emulated device in the Keyboard Mode menu. When a system has multiple keyboards (for example a computer with a terminal connected to a serial port), you can choose which keyboard you want to type on rather than effectively typing on all the keyboards at once. If a system has multiple devices with keyboard inputs, MAME will start with only one enabled by default. Sadly, MAME doesn’t have mind-reading capabilities yet, so it may not always choose the keyboard you want to type on. If you find you can’t type on an emulated computer, check that the right keyboard is enabled in the Keyboard Mode menu. Another batch of layout/artwork system updates are ready this month. More image formats are supported, several long-standing alignment and clipping bugs have been fixed, more parameter animation features are available, and external artwork loads faster. Lots of systems using built-in layouts look prettier, but Cosmo Gang probably shows the biggest improvement in this release (yes, the electromechanical redemption game). Try it out in MAME 0.226, and maybe do a before/after comparison to see how far we’ve come. Apple II systems have seen some significant development this month. Firstly, a number of issues with demos using raster split effects have been fixed. The Apple II has no hardware support for raster effects, so these demos rely on open bus read behaviour to work out what the video hardware is doing. Getting this to work requires precise emulation of memory access timings. Secondly, two parallel printer cards are now working: Orange Micro’s popular Grappler+ and Apple’s Parallel Interface Card. The Grappler+ is well-supported by Apple II software and provides a better out-of-the-box experience if you want to try one of them. Sega’s Tranquillizer Gun was a somewhat ambitious title for 1980, but was largely overlooked at the time. It’s finally fully emulated in MAME, with audio emulation and protection simulation being added in this release. We’ve also added support for Must Shoot TV, an unreleased prototype developed at Incredible Technologies. Step into the shoes of disgruntled ITS Cable employee Chuck and go on a rampage! Far more has been added this month than we can cover in detail here, like another batch of TV games (including several Vs Maxx titles), support for Mattel Aquarius CAQ format cassette images, and working Sega Mega Play games. You can read all the updates in the whatsnew.txt file, or get the source and 64-bit Windows binary packages from the download page. Read the rest of this entry »

Hello guys! I need your help Atari 800, ATARI 800XL/600XL owners! If you guys own a caliber I urgently need to know which size in millimeters (or even better in keycaps unit 1U) the following keys: ATARI 800: - CONTROL key (to my measurements using pictures found on internet) 1.5U - LSHIFT key 1.75U as well as the RSHIFT - FUNCTION KEYS (Select, Start...) 1.5U - CLR SET TAB key 1.5U - RETURN key 1.5U ATARI 800XL - CONTROL key 2.0U - LSHIFT key 2.25U - RSHIFT key 2.0U - CAPS LOWR key 1.25U - RETURN key 1.75U - ESC key 1.25U - FUNCTION KEYS are spaced as 1U keysize. The only correct keyboard I can check is the Atari 130XE style... In attachment the PDF layouts of those keycaps (used by MaxKeyboard) and the keysize in keycap units. Please help me, Gianluca atari-800-xl-style-maxkeyboard.pdf atari-xe-style-maxkeyboard.pdf

Looking at the pictures of the Tomy Tutor MK2 and comparing them against the Radio Schack Color Computer 2 (Tandy), it appears to me that they are using the exactly same keyboard albeit with different key caps. For sure, I've never seen a MK2 in the wild, but considering that the Tomy wanted to produce the Tutor as cheap as possible, that makes sense to me. Wonder if they did the same for the MK1, I think so yes. Looked for the keyboard and the Color Computer 1 also had the chicklet keys, but with differently positioned keys. It would also be interesting to see if the MK2 is compatible with the MK1 as far as the keyboard ribbon cable is concerned.

Hello I just got something in the mail today from a friend. He saw this along his route to work pre-Covid and it was I believe a hundred bucks. First day salvation army was open from Covid he checked and this was something like 10 bucks or less. Since all of our friends that are Circle all look out for each other and help each other when we can and think everyday could potentially be Christmas so we don't have to intentionally go out of our way and feel artificial during Christmas and birthdays, when we treat each other like any day could be potentially a Christmas or birthday. As you can see in the picture it's an intellivision two style keyboard adapter and keyboard, along with the Genesis style one controller and an official Sega 9 pin extension cord. Obviously the first one is the star, but maybe someone modded the Genesis joystick to work with Intellivision. If so that would be kind of cool. May I have a place where there's more information about this on AtariAge? Is there a PDF of the instruction booklet somewhere? I doubt there are many games that are compatible with it. Tell me which ones they are and I'll see if I have them. I also noticed a cassette audio port and an auxiliary port and a remote port and a separate power port. I assume it's not going to work without a power supply. Is that correct? If it does need a power cord may I please have the proper voltage polarity and pin size from a universal adapter?

Hi everyone! Just got my first commodore VIC 20 today! Nice clean looking unit. I'm already enjoying it, but I was surprised to find that a few keys are not working. I took off the keys and I can't get them to work even when I manually press the 'posts' that the keys interact with. Very clean, so that's not the issue. My next step would be to take apart the computer to see if the contacts on the board need cleaning, but then I noticed a pattern: The keys that don't work go every other key on the top row, with the exception of the left arrow key. Even numbers along with '-' and clr/home (mostly sure on the clr/home. Truth told I don't know what it's supposed to do exactly, but it's not doing anything atm) Does anybody with a little more experience than me have any ideas what might cause every other key on the top row to go dead? Thanks for the help!!

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

Hi, I was wondering if there are any technical drawings of the 600XL/800XL keyboards? Not just the keyboard matrix, but things like keycap sizes, spacing, et cetera. I have looked around, but couldn't find any. Or perhaps somebody with a caliper (which is still on my to buy list ) could make some measurements? Regards, Ivo
