Hi - I do not have a TI-99/4A so I have no way to test this. The power supply fits this printer interface however it is not branded as 'AXIOM' so I can not be 100% certain that it is the proper power supply. It was together with the printer interface when I got it so it is likely that it is a match. I have not plugged it in. Please DM me with any offers. Thanks for looking!! This printer interface comes with original box, power adapter and the device itself. There is no manual however, I believe this is the same (or very similar) to the device described here (with scanned manual) https://www.ti99iuc.it/web/index.php?pageid=database_cerca&archivioid=167

A quick post here. I'm going to write more on the CFHDX on my blog soon but I just discovered something cool messing with it. A little back ground, the CFHDX uses software to transfer files between the PC and the TI99 via a cross-over cable. This process works fine but can't print. that requires a DSR with the CFHDX the NanoPEB does not have. But I found a work around and it doesn't use the HDX at all. What it requires is just a VT100 terminal emulator on the PC. You simple set the VT100 to 300,7,odd,none (default for the TI99 RS232) then start the VT100 on the PC and print anything on the TI99 to the RS232. The output is sent to the VT100 screen in all it's 300 baud glory. Use your VT100 to print out the output and you're done. This may be obvious to some people but I thought I would post it as I haven't seen it elsewhere and really does expand the usefulness of the NanoPEB.

I made a PCB to allow me to probe a TI-99 Cartridge in action. It's basically a pass-though with some logic analyzer probe pods with the Address, Data, and Control lines organized nicely. I have one assembled unit and four bare PCBs. Not sure whether to sell assembled, as solder yourself "kits", or just the bare PCB. If there's any interest in these PM me and we can work out the details. I'm limiting this to US buyers with PayPal accounts. That way there is a record of transaction and a way for me to confirm postage and tracking as a way to protect both buyer and seller. Thanks for looking!

TI-99 For Sale w/ Cassette Tape Recorder and Games
Lumberjack posted a topic in Buy, Sell, and Trade
I have 2 TI-99s and 2 TI Cassette Recorders for sale, and a box of 14 game cartridges. You can purchase 1 or both systems. Both are in working condition and I have played all the games. Joysticks and 2 transceivers included. I need to sell these items this week because I’m moving. -
Here is another conversion from my Atari BASIC programs to the TI-99. It's a Yahtzee game. I never liked any of the Yahtzee for the Atari 8-bit so I wrote my own. This is mostly a direct port of that game except for the graphics. On the Atari I used DLI to change the font sizes on the fly which can't be done on the TI-99. But, I used Harry Wilhelm's amazing TML program for some other graphics. TML gives the XB programmer access to the bitmap graphics of the TI video chip. You can create Cartesian point graphics, boxes, circles and multi-colored fonts, loading hi-rez screens and much more. It's similar to the KXB package I used to create Uno with but with much, much more power and, in some cases, more stable. On writing the program. Yahtzee is a fairly simple game so wasn't much to create the original game. the only hard part was the logic to print what could be scored with the roll. the -small straight- logic was most complicated. my solution I thought was rather cleaver. programming the graphics in TML was fairly straight forward. Harry has created a wonderful manual for TML and some examples on the disk. One thing to note, since TML has to, more or less, draw each letter on the screen in bitmap graphics, it a little slower then if I have just used 'display at'. still, it's not all that slow. about average XB slowness. I'm attaching the TML package, my XBEAboot .dsk and the game .dsk. the game auto loads TML then the game. look on the XBboot disk is a program called DT. this is a directory program that runs under TML. and standard DIR program (like the D program also on XBEAboot) won't run in TML. enjoy the game. oh, I'm also including a .vbs script that can be modified to auto load MAME/MESS TI-99 .disk games etc.. from Windows. enjoy. yathzee.zip

Herman Schuurman by Klaus Lukaschek Interview taken December 2015 Herman Schuurman had a 36 years career at Texas Instruments, from November 1977 to his retirement in 2013. In March 1978 he got promoted to be Lead Programmer for the Consumer Products Group in Lubbock. The description of his work is taken from LinkedIn for that designation: Software design for advanced personal computer products. Design and implementation of Text to Speech system based on TMS5200 speech synthesizer; TI 99/4A mini memory development system; I/O section of 99/4 Home Computer; I/O section of BASIC interpreter; system software for various peripheral devices. [https://www.linkedin.com/in/herman-schuurman-60584b9/] Q) What was it like to work for TI in the Consumer Products Group? It was a lot of fun. Lubbock is a relatively small community (around 180,000 when I lived there), so we had a tight-knit team there that also got together outside of work. Lubbock itself is desert-like – dry heat in the summer and cold in the winter. It’s part of the south plains; flat as a pancake, with no hills around to speak of. The names of surrounding towns reflect this: Levelland, Plainview, Shallowater, etc… I was hired in for the Personal Computer Division in Lubbock, but I worked for the Consumer Products Group in Almelo, The Netherlands while my American work permit came through the system. In March 1978 I finally moved to Lubbock, having never actually seen the place. Q) Can you describe your relationship to TI as an employee? You almost worked your whole life there. Until recently, TI had a lot of different subdivisions. This allowed me to work from consumer to industrial systems to research, etc… Lately TI has been concentrating more on analog, so I guess it would be more difficult to stick around for your entire career and still have a variety of assignments. Q) How did it came that you left the Consumer Products Group at TI in 1981? I joined the Dallas-based group that Don Bynum originally came from, the Corporate Engineering Center. By the time I left, most of the system design was over, and the team was moving to application design. Q) Can you describe in detail your involvement with the TMS5200 speech synthesizer? The original design for the TMS5100 was done by Larry Brantingham, Paul Breedlove, Richard Wiggins, and Gene Frantz. Gene was heading up the speech group (home of the Speak & Spell) when I joined TI in Lubbock, and Larry moved to TI France (Nice) soon after. I eventually wound up in a group with Richard Wiggins when I joined the Corporate Engineering Center in Dallas. The second generation of the TMS5100, the TMS5200, was used to power the speech peripheral. My involvement with the speech synthesizer was to create the text translation and allophone stringing software in coordination with Kathy Goudie (who worked for Gene), who was responsible for creating the allophone (sound) set and the translation rules. The linked article by Sharon Crook is basically a rehash of the internal documentation on the text to speech software. Q) All TI-99 Speech Synthesizers have the door that was meant for inserting Speech modules, early units even have an interface for such modules. However no modules were released. Do you have an insight on this? Can you enlighten us with a story about how this was planned and later abonded? The speech module came with 200-odd canned speech phrases that could be used in software modules. There was a provision for phrase ROMs to be added later to expand the available vocabulary, but the introduction of the text to speech capability made that a moot point. Q) Can you describe your involvement in the TI-99/4 project? The Home Computer (99/4) project started about a year before I joined the team in Lubbock. I believe the original promotors of the project were Granville Ott and Len Donohoe. I was originally hired to work on the SR-70, a small scientific computer, but by the time I landed in Lubbock, that project had been moved to the Data Systems Group in Austin, and I was put to work on the SR-62, a small self-contained computer that shared most of its software with the Home Computer. In addition to the Home Computer stuff, the SR-62 had a small built-in monitor and a thermal printer. When the Home Computer eventually fell behind schedule, the entire SR-62 team was moved over to complete the 99/4. Since my background was in operating system design, I worked on a lot of I/O related stuff such as the audio cassette, thermal printer, etc. I also was responsible for the I/O section of the BASIC interpreter, including formatted I/O, etc... One of the more complex peripherals was the floppy drive. Bill Nale and I split that design, with Bill responsible for the hardware and the low level software, while I took the file system design and implementation. This was the only time I remember having contact with anyone from Microsoft, even though a lot of 99/4 websites seem to think that Microsoft was responsible for a lot of the software on the 99/4. We had Bob Greenberg come out once to validate the file system design (there were no design changes). Q) The TI Dimension 4 almost looks like the TI-99/4 and is from 1978/1979. Do you know anything about it? Link for Schuurman to the dimension4 atariage Thread It sure looks like an early 99/4; I don’t remember the Dimension 4 name, but it may be an early marketing name for the 99/4. It was definitely not the Z80-based version, since that looked more like a high-end stereo component, including the wooden side panels. Compared to the 99/4 it was extremely fast, since the video was memory mapped (and you had a speedy processor). Before I arrived in Lubbock, there was some work done on a native GPL chip, but by 1978 that had been replaced with an 8-bit TMS9985 based design. Unfortunately, that chip never ran correctly, so we had to eventually fit a 16-bit TMS9900 into an 8-bit design. If you like to see more info on the 9985 design debacle, check out Karl Guttag’s page at http://www.kguttag.com/2013/08/10/if-you-havent-tested-it-it-doesnt-work/. Q) Do you still have a TI-99? If yes, can you describe what you have kept. When was the last time you used it? A few years ago I gave all my 99/4a related hardware and software to Joe Zbiciak, since I hadn’t touched it for quite a while. Joe is more into legacy systems, so he had a better use for it. I kept the Panasonic monitor, but it failed a few weeks ago, so now I’m totally out of 99/4a related stuff. Q) Was your Text to Speech system reused for other Speech products from TI or other companies? Not to my knowledge. A remember Ute Marcotte was working on a German version of the text-to-speech rules/allophone set, but I don’t know if that ever made it out. Most of the later interest seemed to be in speaker independent speech recognition, which I worked on several years later in the Telecom Systems group. Q) Having some relationship with Speech, what is your opinion on Apple's Siri? Compared to the early work we did on speaker independent speech recognition, both Siri and Cortana are phenomenal. Of course the amount of CPU power and available memory space are also incomparable. I use the speech recognition on the iPhone quite a bit, and it is really good. Q) Does your name have an origin in the Netherlands or some close-by country? Can you enlighten us? I was born in the Netherlands and spend the first 24 years of my life there. I graduated from the Technische Hogeschool Twente (now known as the University of Twente) in Enschede, the Netherlands. After graduation I joined TI and moved to the USA. Although I graduated in Electrical Engineering, a lot of my background was in embedded systems and Operating Systems design/implementation, which is why I was hired by TI. Q) Do you know how it came that the command to load a program is called "OLD" on the TI? It probably came from the original Dartmouth BASIC, where OLD was used to retrieve a program from storage, and NEW to start a new program. Q) Bill Cosby was the front face for the TI-99 to the public, was it a person the employees looked up to as well? Advertising was all handled by the marketing team, but Bill Cosby was very popular in those days, both from his earlier I Spy series, and through the Fat Albert and the Cosby Kids show. In addition, the fact that he had a Doctor of Education degree didn’t hurt. Q) What was the role of Don Bynum you worked with? Don was working on a redesign of the 99/4 while in the Corporate Engineering Center in TI Dallas (the Ranger). In late 1980 he moved to Lubbock to take over the home computer group from Pete Bonfield (who moved on to become Chairman and Managing Director of ICL in England). He drove the 99/4a and peripheral box efforts, and later the 99/2 and 99/8. I never actually saw it, but he was rumored to have an old piano cabinet with the 99/4a peripheral chain taking up the entire cabinet. A few months after the introduction of the 99/4a I moved from the Lubbock team to Bynum’s old group, the Corporate Engineering Center in Dallas. Q) Was it clear from the beginning that there will be some Text to Speech software or was it some brilliant idea by an employee? I don’t know who came up with the text-to-speech idea with the speech group, and Kathy can’t remember either. I’ll check with Gene Frantz to see if he still remembers. Keep in mind that it was not a given that text-to-speech would actually work acceptably in the 9900 until we actually implemented it. Q) So we could say, that your work on the Text to Speech made the speech modules for the Speech synthesizer irrelevant, right? Yes. Q) On what scientific work was your Text to Speech software based on? Was there any linguist or phonetic scientists involved? TI already had an active speech team located in the Lubbock (one of their best known products is probably the Speak N Spell). The person I worked with, Kathy Goudie, has a Ph.D. in Linguistics, and the allophones used in the text-to-speech software were created from an extensive speech database that had already been developed within the speech team. Q) I couldn't find much information on the SR-62 and the SR-70 computers, have they ever been released? What have the specs of the SR-62 been? Since you said it should have shared its software with the 99/4, this might be interesting for our people to know. Not surprising, since these are internal designators, and neither product ultimately made it to market. The SR-62 was essentially a self-contained home computer with a built-in monitor and a thermal printer. Q) Do you know how much Microsoft or Bill Gates was involved in the TI Basic / System Rom of the 99/4? Microsoft was not involved with the 99/4 development. They (in the form of Bob Greenberg) were contracted to develop BASIC for the SR-70 (which is also sometimes referred to as the 99/7), but the BASIC for the 99/4 was developed in-house. Q) Why was the native GPL chip replaced with the TMS9985? How far was the GPL chip developed? Although it was before my arrival in Lubbock, the GPL chip was supposed to be developed for an external customer. When that customer dropped out, the GPL chip was also dropped, and was replaced by the TMS9985. Q) Accessing peripheral devices through a DSR interface allows us to connect modern devices to the TI without modifying the System Rom. Do you know who came up with the idea on this? Did TI had that before the 99/4 already? It’s been too long to remember the exact details, but it was probably worked out between Bill Nale and me. Bill would have handled the level 1 features (hardware communications, sector read/write, disk formatting), and I would have handled the file related features. Since the hardware was developed concurrently with the software, it allowed me to work on the file system code by simulating the low-level routines on a TI-990 minicomputer, using a large file on the minicomputer hard drive to simulate a floppy disk. Keep in mind that I already developed a similar system for an Intellec-80 (Intel 8080 based) system using 8” floppies as part of my thesis. Q) How did you feel when you heard that TI will leave the home computer market after being involved in setting it all up? Sad, although it was probably inevitable due to the financial losses. I’m still glad I had a chance to work on it though. Q) What was the policy of TI with hardware/software/documentation/schematics on canceled projects? It seems a few lucky employees got a TI-99/8 when TI left the market. Typically you have to get official permission to legally get any of this stuff. That said, it is entirely possible that management at that time gave away some memorabilia. Q) How do you feel when you hear that those machines are still running after all those years and there are some people still doing stuff with them? Absolutely amazed and delighted. I would have never guessed the 99/4 would survive for over 35 years, especially with the typical rapid turn-over in the computer age. Best Regards, Herman Schuurman

MAME TI 99-8 & TI 99-2 full usable download I have put together a workable MAME TI 99-2 & TI 99-8 packages. Just download and execute the batch file in the MAME directory. The 99-2 & the 99-8 never made it market for TI but they got fairly far along to the point of workable prototypes and even manuals (download manuals from http://ftp.whtech.com/datasheets%20and%20manuals/ ). The 99-2 works fine as is. It only has 4k of memory, no sound and B/W. Bo sure to use only the disk in the DISK directory. The sectors are different than the standard TI .DSK files. To access the disk use: OLD HEXBUS.101.SOMEFILE to save files use SAVE HEXBUS.101.SOMEFILE (somefile is your file name). there is a small file on the DISK BASIC-proj.DSK (the batch auto loads this disk) named HELLO. To load type OLD HEXBUS.101.HELLO In the batch file I kick off a text file that pops up next to the MAME screen with the 99-2 function keys and a vbs script that turns on the upper-case when the 99-2 starts and turns it of when the 99-2 ends. All this pertains to the 99-8. What is different about the 99-8 is the requirements from the PC. A i5 or i7 is required to work fast enough. I have set the 99-8 to work with my i3 in the batch file by skipping 1/2 the frames with -frameskip 30. If you have a i5 or i7 you can reduce this or eliminate it. Also, to keep the sound from stuttering I have set -audio_latency 34. If you have a faster machine, again, this can be changed of eliminated. I you have a PC slower than a i3, forget about it. Download the latest MAME at https://www.mamedev.org/release.html then add the data from the .ZIP files to the MAME directory. Here are the files: TI99-2.zip TI99-8.zip Have fun, HLO

http://www.2600connection.com/features/parsec/parsec.html Atari Connection is creating a cartridge of my Atari 2600 game based on TI-99 Parsec. He has done a really nice job on the cartridge and manual. The game has swoopers, backward swoopers, single Bynite type enemies, meteor shower and even a refueling tunnel. I had a lot of fun creating this version of TI-99's Parsec for the Atari 2600 and I think it turned out alright. It's a limited run of about 20 at a price of $25. I can't wait till I can put my Parsec 2600 in my 2600. There's just something about having a physical cartridge with label, manual and all. FYI: I also wrote the manual. HLO

Hi all, I'm trying to put the finishing touches on my "maxed out" TI-99 setup. All I need is the power supply for my TI acoustic coupler modem, and I'll be done. Does anyone have a spare they'd be willing to part with? The model number is 901017, output is 20V AC, 400mA. I've heard it's the same as the one used on the Atari acoustic modems. I'd also consider purchasing a second modem with power supply, if someone has one they'd consider selling. I also have a second TI-99/4A console, but the keyboard is damaged (broken keyswitch and missing keycap). This is one of those earlier black keyboards. I'm looking to either repair the keyboard, or just swap in a fresh one. If anyone has a parts keyboard, or just a spare, I'd be interested in negotiating. Any help is appreciated. I'm including pictures of the modem power supply, which is apparently somewhat unusual.

In a package deal I received this TI 99/4A computer. I figured I would play with it a bit but once I opened the box, I came across a dilemma: it looks very new!! This stuff isn't common so I don't have the heart to break the seals and use it. The computer bag is open, but since the peripherals are sealed I can't imagine it was ever used. All the paperwork looks perfect too, so I'm not even sure if the computer was taken out of the box. I'm looking for $100 shipped for it. Also interested trading for (give or take credit): GBA Everdrive SD2SNES USB GD-ROM VGA/HDMI Box for Dreamcast Legos Album: https://imgur.com/a/TFq5d Thanks for looking.

Hi, I've recently begun fixing an old nonworking TI-99/4A and concluded that the problem I'm facing most likely is in the RAM section of the board. Before I buy new RAM chips I'm wondering what the difference is between models. I have the MK4116N-2GP chips but I can only find MK4116N-2 chips. Can I replace the old ones with a different model?

I have seen those tape/floppy drives that slot into the cartridge slot looking space on the side of the unit, but I have been having a hard time finding them on Ebay and when I do, they are always very expensive. Are there any other ways to do this?
