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)

I want to write a EA5 program loader in Assembly and hoping for a bit of guidance. While I could leverage code from another application, I would prefer writing from scratch, so I fully understand the process. I also don't want to rely on the internal EA loader so as to keep access to all of low memory. It's not all that hard to read the program header, push it into memory, read the next program header, push it into memory, etc, then point the program counter the starting address of the program, but then what next? So, if anyone is aware of any articles or sources that I could refer to I would appreciate it. Thanks, Ernie

I have for sale a TI 99/4A 32K sidecar, two multicarts of TI games, and a TI cart of Jet Set Willy, all of which were or are sold through the Arcade Shopper website. About the items: -The 32K sidecar does not have its external power supply, but still works when attached to the side of the TI-99po. The power supply would be needed, however, if you were to attach it to something already attached to the TI (like the speech synthesizer, for instance) and also did not wish to perform an additional modification to the sidecar. With this sidecar (or another source of 32K memory) you can play the three other carts offered for sale here, among others. More on the sidecar here: 32k sidecar memory expansion (arcadeshopper.com) -The TI multicarts are the 2048k Games #1 and the 512k Games #6 carts and you can read more about what is on them (in short, a lot of TI-99/4a games) on the Arcadeshopper.com website here: Multi-carts (arcadeshopper.com) -Jet Set Willy, a port of the ZX Spectrum game, is also offered for sale as part of this lot. All have been tested with the 32K sidecar. Asking price for the lot is $119, with shipping included in that total. Payment would be through PayPal. Thank you, Dave O'Connell

SOLD: Star Trek TI-99/4A Cartridge Variant (HTF)
sixersfan105 posted a topic in Buy, Sell, and Trade
Here we have an extremely hard to find cartridge variant of Star Trek for the TI-99/4A. This cartridge is only the second confirmed cart with this label type. There is no date listed on the back, but the working theory is that Triton Products distributed this cartridge type in the 1984-85 timeframe. Triton Products had the rights to manufacture TI cartridges using leftover parts received from TI when they purchased the distribution rights for all remaining TI hardware and software stock. It looks like this run of cartridges was complete with the exception of the labels, so they made the black text on white background label. It is listed on 99er.net as UR for "Unbelievably Rare - A cartridge thought to never have existed, but has been found and proven it does exist." Please send me a PM if you're interested or would like some additional pictures, and we can also discuss pricing. Thanks! SOLD!

Time to start downsizing... I have three cartridges, Pole Position, Moon Patrol and Donkey Kong that come as a trio. Shipping will be USPS flat rate box with bubble wrap. Asking price (shipping included) is $40.00 because shipping prices suck, so my I'm actually taking a loss on what I paid for the cartridges, but I don't need them anymore. This is a photo of the cartridges. P.M. me if interested, price firm. Due to work, the earliest I can ship will be Tuesday afternoon. Paypal only. Update: SOLD

I'm looking for the following seven games from "Compute!'s Creating Arcade Games on the TI-99/4a" by Seth McEvoy: 1) Martian Attack 2) Martian Revenge 3) Riverboat 4) Shark 5) Mushrooms 6) Hobo Party 7) Moneybags Here's the book's cover: A pdf of the book is here: https://archive.org/details/tibook_creating-arcade-games-on-the-ti994a/mode/2up Here's the book's table of contents: I've looked around for these TI BASIC games, but I can't find them. I'd like to try them. I know that they'll be simple, but I'm curious about what this book hopes to teach the reader. Did anyone here use and read this book? Does anyone have some or all of these seven TI BASIC games on tape or disk? Adam

Due to the COVID-19 Pandemic the Chicago TI User Group has decided that the Chicago TI International World Faire will be held online this year, rather than in person. Accordingly, we are now soliciting presentations in video form, to be presented at the virtual Faire. At this time we would like to ascertain what interest this is in the TI community. Anyone who has the desire to produce a video on a TI topic should send a private message to hals12@hotmail.com in the next few days indicating the nature of the presentation, and we will get in touch with you with the details we require. Thanks in advance. -The Faire Committee chicagotiug@sdf.org -
I don't know how much cross-over there is in this TI-99/4a sub-group with the Atari 8-bit home computer sub-forum, but I presume since this forum is hosted in the AtariAge forums that there must be at least a few people who collect for both computers. Right now, I have a six books for books for the TI-99/4a computer. They're the one's in my first TI video: https://www.youtube.com/watch?v=eoBjUDMar84 I'm looking to expand the TI books that I have currently in trade for spare Atari books that I have in my personal collection. Is anyone interested in doing trading books with me? If so, then I'd like to use this thread to post the books I have, and others can post the books that they have for trade. If a few people like this idea, then over the next few days I'll make a list of TI books that I want and a list, maybe with pictures, of the Atari books that I have for trade. So... is anyone interested in trading their spare or unwanted TI books with me? Adam P.S. Oh, and if you have no interest in Atari books, then you can always give your spare TI books to me...

p-box Plug & Play - Replacements with possible updates.
Omega-TI posted a topic in TI-99/4A Computers
Mean Time Before Failure - It's starting to look like this is beginning to effect more and more P-Box power supplies. Preemptive Maintenance - Fixing the situation before it destroys something else more expensive with it's failure or, puts one out of service. Plug & Play - Designed so even the least technical people in the consumer market will feel comfortable installing it, ensuring more sales. Limited Targeted Market - Niche markets, usually have test markets or single runs of a moderate size to keep costs down. I'm thinking it may be time for "someone out there" to consider a viable Plug & Play replacement for the P-Box power supply. 1 - Could the cost be reasonable? (How much are you willing to spend for an easy replacement to protect your equipment) 2 - Could it be a direct replacement, not requiring any other modifications from the customer. 3 - Could there be "an extra" on the board as a further inducement to purchase? (Example: USB power port) -
Looking to unload my duplicate TI-99/4A cartridges. Most are cartridge-only but I have a good number of manuals, too, and also have four box + tray sets and two additional boxes (without trays), so we can put together complete in box (CIB) sets of your choosing, based on supply of manuals and such, just let me know what you're looking for. Also have some manuals without their corresponding carts that I'd be happy to sell, including manuals for Buck Rogers, Defender, and Zero Zap (modern style), among others. Note that Atarisoft carts are listed separately below the "first party" TI cart list. A-MAZE-ING (beige cart, red label) A-MAZE-ING (black cart, black label) The Attack (black cart, black label) Blackjack and Poker (black cart, black label) Blasto (black cart, red label) Blasto (black cart, black label) x 2 Car Wars (black cart, black label) x 3 Chisholm Trail (black cart, black label) x 2 Congo Bongo (beige cart, red label) Home Financial Decisions (black cart, black label) Home Financial Decisions (black cart, purple label) Jawbreaker II (beige cart, red label) Microsurgeon (beige cart, red label) Moonsweeper (beige cart, red label) Munchman (black cart, red label) x 2 Parsec (black cart, purple label) x 2 Popeye (missing label) Speech Editor (black cart, black label) TI Invaders (black cart, red label) TI Invaders (black cart, black label) Tombstone City (black cart, black label) Video Chess (black cart, black label) x 2 Dig Dug Donkey Kong Pac-Man Picnic Paranoia Shamus I would be happy to provide pictures and prices via PM. The more cartridges you buy, the greater the discount. Guaranteed to be lower than eBay. Also don't hesitate to reach out with interest in manuals, as I mentioned I have several. Thanks!

I posted a scan of a photocopy of the SDS Programmers Guide in the Development Resources sticky, but it was suggested I start a new thread, so here it is. I have some other stuff, SDSMAC source listings, additional documentation, etc. to put here, too. Coming soon. Anyone else have anything relevant, please post away. The SDS consists of a GPL assembler, linker, simulator, and debugger running under DX10 on a TI 990 mini, typically a /10. TI BASIC programs can be converted to GROM format to run on the simulator. [edit] Anyone has a copy of the SDS software or even a running system, or knows where such might be, please post here, message me, or email jbdigriz@dragonsweb.org. Thanks! jbdigriz HCM_SDS.pdf

I've got a spare Treasure Island for the TI-99/4A, complete in box with cartridge and manual. Cart is fully cleaned and tested and works great. Asking $25 shipped. SOLD! This is one of the harder to find "first party" games for the TI, as it only had a limited run towards the end of the computer system's lifespan. The graphics are great and it's a lot of fun! Please see pictures for exact condition of all items. Manual has the item number cut out on the back right, as is commonly seen with TI manuals due to their giving out freebies for X number of games purchased. The box's plastic is broken a bit on the sides where the seal was originally broken. It says "Saturday Night Bingo" on the sticker on the back of the box. Will ship via USPS in a carefully packed box. Please send me a PM with any q's or to purchase.

Hi, I am trying to fetch *all* dates of former meetings, to sort the pics I´ve gathered together. If you know about more dates, please let me know, so I can create empty folders, as a first step. And maybe just have some place here, to post old pictures... or send them to me via PM, and if not wanted to publish here, or if HiRes, just send them to 99er@toxic-instruments.com thx PS: Here are the dates I know about, and wether they were INTernational,REGional, or whatever. Pls see the foldernames. "empty" means, I know the date, but have no pics.

Here we've got a TI-99/4A computer in its original box. Everything has been fully tested and works great, except where noted below. Please see provided pictures for exact condition of all items. Here's everything you get: TI-99/4A original black and silver model with box. All keys work. Fully play-tested with multiple games. Cosmetic issues include some scratches and the brushed aluminum top casing is coming up a bit on the front left side. The original box is worn. Joysticks - A pair of dual original TI joysticks are included but don't recommend using them. One of them is missing the stick part (but fire works!) and the other joystick works, but the "up" direction requires a little extra effort. It'll work in a pinch for one-player games, but I recommend purchasing an Atari joystick adapter ($10-15, my favorite is this one, which is also on eBay for slightly more $. That adapter can also be beautifully paired with this 3D case, if you're so inclined) so that you can use Atari-compatible joysticks of your choosing. Another great option is @RetroGameBoyz's TI gamepad. It works for single player only, or you can buy one of his Atari pads and use them with the aforementioned Atari adapter. The joystick port has been further tested with my personal TI joysticks and everything worked perfectly. Original OEM power supply - works as it should. Lots of manuals - User's Reference Guide, Beginner's Basic, Read this First, Teach Yourself Basic cassette manual, TI joysticks manual, and a TexNet flyer. Keyboard "strips" x 2 which you can write on for keyboard shortcuts (no strip holder, however, but the strips still sit on the computer fairly effectively). Miscellaneous - an untested OEM cassette player cable, in case you opt to get a cassette deck down the road, along with untested Teach Yourself Basic on cassette (two tapes). If you can't tell by now, I don't have a cassette deck/"TI Program Recorder" to test this cassette stuff with. Original OEM RF modulator does not seem to work but it is included for completeness. The good news is that composite monitor cables are readily available on eBay and are better than RF, anyway. I've always had success with Atari monitor cables. I just don't have a spare at the moment. I'm asking $50 plus shipping but I can be flexible if need be. Looking for some TI games, too? I have a bunch of extras. A full list is available here. Shoot me a PM and we can come up with a great discounted deal for you as part of a larger bundle with this computer. Let's put something together for you to get your TI-on!

I got my first-ever TI-99/4A last fall and have been enjoying it immensely. That said, since I have it in use all the time, I don't have any need for the AWESOME travel case that it came in. I have no idea of the history of this item, other than that the foam cutouts are clearly made for the TI-99/4A and its components. Here are some pics. Since it appears to be a unique item, I have no idea what to ask for it, so let's give "best offer" a try and go from there. Any q's and to make an offer, please shoot me a PM. Please note that these pictures are for display purposes only and you would only be purchasing the case itself with the padding - no TI-99/4A computer or accessories. Thanks!

SOLD: Texas Instruments TI-99/4A Computer Bundle
sixersfan105 posted a topic in Buy, Sell, and Trade
Here we have a Texas Instruments TI-99/4A Home Computer Bundle. The computer has been lightly cleaned and fully tested and works great! Don't roll the dice on an untested unit when you can purchase this fantastic starter bundle with confidence! Includes everything you need to get your retro gaming on as soon as the package arrives at your doorstep. Here's everything you get: TI-99/4A Computer (original black/silver model; 1983 production date) TI Speech Synthesizer TI Power Supply TI RF Modulator (even includes a push-on F-type balun for more modern TVs) TI Dual Joysticks Original Box with Styrofoam Insert Five (5) Complete in Box Games: Parsec, Munch Man, Tombstone City: 21st Century, Car Wars and Zero Zap - all tested Several Manuals/Reference Guides: User's Reference Guide w/Addendum, Beginner's BASIC, Read This First w/Addendum, BASIC Reference Card, Wired Remote Controllers and Video Modulator manuals, TI-99/4A Owner/User Information Card,TexNet Information Services pamphlet and TI Computer Advantage Club flyer During testing, one joystick worked as it should and the other only worked in the "left" and "down" directions. Considering the stock joysticks aren't very good, anyway, it is recommended that you purchase an Atari joystick adapter and use your favorite Atari-compatible joysticks instead. While the RF modulator works, it is recommended that you upgrade to a composite AV cable. Such cables are pretty inexpensive and readily available. As evidenced by the close-up picture, the cord of the modulator that plugs into the computer is starting to fray a bit. The keyboard strip, while present, is just sitting in position, as a strip holder is not affixed to this computer. The computer box has seen better days but still holds its shape fairly well. As seen in one of the pictures, a prior owner cut out the bottom end of each of the five game boxes, most likely for easy access. "Zero Zap" is handwritten on the side of the Zero Zap box; "Hangman" is handwritten on the side of the Tombstone City box. While several minor flaws have been identified, please see pictures for exact condition of all items. Asking $110 plus shipping OBO. Will ship in a carefully packed box via USPS Priority Mail. Please let me know if you have any questions or would like to see additional pictures. ***Cross-posted on eBay***

This is a more targeted continuation of the blatantly hijacked thread <here>. Executive Summary of this go-forward: The NanoPEB being periodically peddled on eBay is a wonderful little device, providing 3 virtual disk drives which map to a Compact Flash card, a 32K RAM expansion, and an RS232 serial port. Unfortunately, the serial port was set up in such a way that virtually all existing Terminal Emulation software packages take one look at that serial port, and promptly throw their dish on the floor. The technical details of that I leave to vaster minds than mine to explain. Meanwhile, I have slapped together what I think is a toy many of us would like to have and use, a WiFi modem that is RS232 compatible and doesn't cost an arm and a leg. The prototype has been proven with several IBM-ish 8088 machines, and I have been surfing Telnet BBS's with it. I would like to test and use it with my TI-99/4A plus NanoPEB, but the terminal software always stops me, since none of them like my serial port. My current quest is to find, make, beg, borrow, steal or barter a package into working with the NanoPEB. The ultimate goal is to publish details of this very simple modem, so that others in this community can make their own for less than $10 and a few minutes work, and go BBS surfing using their household WiFi, Telnet, and a T-99/4A with either an "original" serial port or a NanoPeb. I'll explain how once it's tested, as I don't want folks clamoring to build one only to find that it doesn't work in this plane of existence. The modem itself works in another environment, but I'm a firm believer in end-to-end systems testing. Besides, I have a NanoPEB, so I'm greedy and want it to work with my TI-99/4A. So that's the lay of the land. In our last episode (thread) InsaneMultitasker had generously thrown me a software package thinking it might work. I'm sorry to report that it doesn't. It runs well up until the moment any byte is actually sent down the line, then it crashes. (Cursor stops blinking, and no keys respond.) To be thorough I connected a null modem cable between the NanoPeb and the modem, (they normally dock directly), but the behavior was the same. The quest continues,... -
Here's a little device I bought on ebay. Got it out of curiosity really. Costed me 40 EUR including shipping in Germany. It's a centronics interface that plugs into the sideport. Basically what interested me most is what DSR is included. Appears to have costed 299 german mark back then. That is according to the "Kaufhof" label that is still on the original box. Probably boils down to 300 EUR nowadays. I scanned the device using my own DSR scan program, but nothing shows up. So either the device is broken or it needs power from an external source (the centronics interface?) Anyone else seen such a device before? At least it's new to me. Centronics would be matrix printer style right?
