RenegadeR Posted June 8, 2018 Share Posted June 8, 2018 Hello Guys, I am trying to get back into the TI-99/4A which was my first computer and this is where my love for programming started. So I bought one from a local website and I was very happy to see that it looked amazing but the problem is that it doesn't boot I just got a black screen and continuous beeping sound, and after I told the seller he did not replay back I have been trying some stuff to fix it, after looking at a couple of threads here and getting some troubleshooting manuals I ordered a TMS9929ANL from ebay and replaced it and the problem is the same, also I saw some people mention the MCM6810P ram chips so I also ordered those and replaced them and still it acts the same. Could it be the GROMs? I cannot find them anywhere, the CD2155NL, CD2156NL and the CD2157NL does anyone have some of these and are willing to sell them? Anyways any kind of help is welcome, I already got my FinalGROM 99 cartridge from the amazing Ralph Benzinger but that will have to wait until my TI-99/4A works. Thanks!

RenegadeR Posted June 8, 2018 Author Share Posted June 8, 2018 Thanks! And I am happy to tell you that my TI-99/4A is fixed now!! So it seems it was one of those MCM6810P, now it works perfectly also the FinalGROM 99 is amazing all the games that I never could buy when I was young I can play now. Can't play many of the homebrew as it seems you need 32K for that so that will be my next purchase. 3 Quote Link to comment Share on other sites More sharing options...

digdugnate Posted June 8, 2018 Share Posted June 8, 2018 welcome back! i think personally the barrier to entry is fairly easy to overcome- won't take a lot to get a 'full' system Quote Link to comment Share on other sites More sharing options...
RenegadeR Posted June 10, 2018 Author Share Posted June 10, 2018 So I think a 32kb memory expansion and a speech synthesizer and a joystick splitter so I can use my C64 joysticks. That should be enough to play most games? Quote Link to comment Share on other sites More sharing options...
digdugnate Posted June 10, 2018 Share Posted June 10, 2018 i would think so! Quote Link to comment Share on other sites More sharing options...
