timofonic Posted June 14, 2017 Share Posted June 14, 2017 (edited) What EDA software have you used? Do you plan to release the design files on a place such as GitHub? It would be interesting for people into electronics, even modifying it to "break" the 1983 rule (replacing memory chips with higher density ones, using CPLD or FPGA, integrate updates, convert it into a Geneva, etc).

barry.peterson Posted June 14, 2017 Share Posted June 14, 2017 I also would buy one in a heartbeat! Quote Link to comment Share on other sites More sharing options...
JonnyBritish Posted June 14, 2017 Share Posted June 14, 2017 Forth Amazing to see this. You could almost imagine a bunch of other retro consoles done in same way ie VCR style so you could stack them Great work! Quote Link to comment Share on other sites More sharing options...
PeBo Posted June 14, 2017 Share Posted June 14, 2017 (edited) Fabrice, As always, your custom builds are stunning creations. This one is no exception. In fact this one sets a new level. You have more imagination and talent in you baby finger, than most of us have in our whole hand (in our whole bodies to be honest) I stand in awe. Absolument incroyable Monsieur Montupet! Oh and I used edit to add this: Does this mean I can have your modded beige console now????? (SVP!!!) Edited June 14, 2017 by PeBo Quote Link to comment Share on other sites More sharing options...
+chue Posted June 14, 2017 Share Posted June 14, 2017 Like the others I too am in awe of this project! Just one question though... which side is the coffee warmer on ? 1 Quote Link to comment Share on other sites More sharing options...
fabrice montupet Posted June 14, 2017 Author Share Posted June 14, 2017 Thank you all of you very much for your kind words ! I'm happy to see that this TI(ny)99/4A is appreciated :-)@Rasmus: The v1.0 TI(ny)99/4A is design for PAL TMS9929A VDP so, at this stage of the developpment, it is not really compatible with the TMS-9928A: their color table are different. So, by installing a 9928A you'll get a picture but wrong colors.But a 9928A compatiblity is an interesting future option to add to the motherboard.@--- Ω --- : The jumper you see is for I/O data bus control, not for disabling the 32kb expansion RAM, but it is easy to disable the 32Kb to be able to use a SAM :-)@timofonic: I used Diptrace. At this time, I am not planning to put the file on GitHub or equivalent.@PeBo: With this TI(ny)99/4A my modded TI-99/4A suddenly gotten old ! That said, I think that I will still keep it a bit. But it is quite possible that I will part with it one day.@Chue: A coffee warmer, this is a great improvement to add to it ^^ 3 Quote Link to comment Share on other sites More sharing options...
apersson850 Posted June 14, 2017 Share Posted June 14, 2017 You do know that "coffee warmer" is the common phrase for the hot area below the cartridge port in a standard TI 99/4A, don't you? It's funny that in Swedish, TI(ny) reads like TI(new), and this is really new in spite of being old, if you get my drift. Quote Link to comment Share on other sites More sharing options...

matthew180 Posted June 15, 2017 Share Posted June 15, 2017 Oh cool, you used DipTrace. I went through a big electronics designs software review/decision making process a while ago and DipTrace was very high on my list. I almost bought it, but Altium had just released CircuitMaker so I decided to try that first. Needless to say I'm still using CircuitMaker and really like it. How do you like DipTrace? Are you happy with the software after doing a large project like this? Quote Link to comment Share on other sites More sharing options...
samishal Posted June 15, 2017 Share Posted June 15, 2017 Holy crap! Fabrice this is incredible, I'd love to build one of these myself, very nicely done! Quote Link to comment Share on other sites More sharing options...
JamesD Posted June 15, 2017 Share Posted June 15, 2017 If you think about it, this is almost a miniture version of TI's mini-computers. A mini-mini if you will.Ya know, TI probably would have been much better off making a design like this and charging $1000+ for it. 1 Quote Link to comment Share on other sites More sharing options...

fabrice montupet Posted September 10, 2017 Author Share Posted September 10, 2017 (edited) Thank you all! Since my new job, I am not much available. But, I would like to show you the extended keyboard I made for the TI(ny)-99/4A: Here is, too, a view to the second motherboard I made: Edited September 10, 2017 by fabrice montupet 14 Quote Link to comment Share on other sites More sharing options...

+jedimatt42 Posted September 18, 2017 Share Posted September 18, 2017 Reminds me of the GR8BIT computer... All vintage chips. I love it! Getting the classic PEB port in there for compatible expansion is truly awesome! Looking forward to seeing where you take it. This truly shows passion for the TI! -M@ Quote Link to comment Share on other sites More sharing options...
oddemann Posted September 18, 2017 Share Posted September 18, 2017 Me like!So cool that you put "everything" into a box.I am pretty sure you would sell a few of them if you wanted. Pretty sure you would sell a lot if you made "modern" fix on that design. Like someone said, more ram, memory card options, HDMI. I think that a "gamer" like that would have a good platform to have more stuff created on it. Like "The second coming" hehehe Even I would want to buy it and share old memory's with my kid. Power on and your ready to play games - Very hard to resist One thing is for sure - It is great, cool design and so cleanly executed.

LASooner Posted September 18, 2017 Share Posted September 18, 2017 Is there going to be thermal issues with such a compact design and old components? Quote Link to comment Share on other sites More sharing options...
speccery Posted September 19, 2017 Share Posted September 19, 2017 What a thing of beauty, really amazing work Fabrice! Like it was said earlier in this thread, this build really raises the bar. ..and makes me wonder if for the next project I should go more retro and just use components from the day. I did not yet look at this closely but will do so later, just curious on what type of memory chips you used from RAM and ROM? Quote Link to comment Share on other sites More sharing options...
fabrice montupet Posted September 23, 2017 Author Share Posted September 23, 2017 (edited) Thank you all ! :-) Pretty sure you would sell a lot if you made "modern" fix on that design. It is not my goal, my only goal is to make me happy :-) My electronic realisations concerning the TI-99 will never integrate modern component. If I want to use modern tecnology, I use my Intel Core i5 iMac, Macbook Pro or PC computers. Like someone said, more ram, memory card options, It is panned on the next version. The v1.0 was made to validate the good operation of the Tiny99/4A computer according to the (numerous) corrections I made on the TI-99/4A schematics that are false. I took the opportunity to bring some improvement to the TI-99/4A like size, speech, 32Kb RAM, RGB signal, expansion possibilities and speed. Is there going to be thermal issues with such a compact design and old components? No thermal issue :-) I use the TI(ny)99/4A during many hours per day without note abnormal hot temperature. Even in turbo mode. Edited September 23, 2017 by fabrice montupet 6 Quote Link to comment Share on other sites More sharing options...
