grayin99 Posted October 27, 2020 Share Posted October 27, 2020 Another one of those guys who had a Ti-99/4A in the 80s that felt nostalgic and bought one recently to relive old times. I probably spent too much, but I got a working system with a 32K expansion and FinalGrom off of Ebay recently. Also found another console at a garage sale that works. So now I have two (both in silver/black). Last time I had a TI-99/4A was in 1985. Bought it on clearance (Sears I think). Had a lot of fun back in the day with a few cartridges, cassette recorder, and lot of typing in of Basic Programs. The Navy, lots of moving around, and newer computers made me eventually stop using the 99 and it unfortunately vanished in one of my moves. I probably don't have much to contribute to the community, but I did make a small remix of the JediMatt42 case for the 32k/Tipi sidecar. Only real difference is the Texas Instruments logo in the side. https://www.thingiverse.com/thing:4625910 Now to start reading up on things. 15 Quote Link to comment Share on other sites More sharing options...

+TheBF Posted October 27, 2020 Share Posted October 27, 2020 Welcome Grayin99. I think you will find that the resources available are incredible compared to when we first bought our machines. Also the level of talent assembled here never ceases to amaze me. 2 Quote Link to comment Share on other sites More sharing options...

I think you'll love your "second time around" more than the first. Back then you either had to wait a month for a magazine, a user group meeting or possibly a few contacts on a BBS if you were lucky. Now here at AtariAge, you'll find people online nearly 24/7 from around the world that have some truly staggering in-depth knowledge about this system that they are willing to share and help answer questions. This place never seems to get boring, someone always seems to have something new to keep things fresh and exciting. 2 Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted October 28, 2020 Share Posted October 28, 2020 There are two versions of Forth that run on the Geneve. One is by Mike McCann (and used with The Printer's Apprentice, The Geometer's Apprentice, and HQ Stacks), the other is Forth+ by Bill Sullivan. It was a further development of Mike's version, IIRC, and Mike's was a further development of TI Forth. 1 1 Quote Link to comment Share on other sites More sharing options...
Retrospect Posted October 30, 2020 Share Posted October 30, 2020 The people on here are fantastic you'll enjoy it. I've seen old software turn back up thanks to people here finding it, and I've seen lots of new software that is brilliant, some of which you'll never have thought possible on the TI994a. Welcome aboard. 1 Quote Link to comment Share on other sites More sharing options...

Omega-TI Posted October 30, 2020 Share Posted October 30, 2020 Just out of curiosity, has anyone out there printed one of these up and painted it match the original Peripheral Expansion Box light & dark silver silver motif? Quote Link to comment Share on other sites More sharing options...

The original of this by JediMatt42 (without the emblem) is silver in this picture: https://www.thingiverse.com/thing:3919115 Might be a little too shiny to match or the flash might make it look like that. I have some greyish/silver filament I thought about trying on this. Would have to add the black highlights with paint.

In my opinion not enough people share the eye candy. 1 Quote Link to comment Share on other sites More sharing options...

In my opinion not enough people share the eye candy. Here is a silver/grey version I printed using Hatchbox PLA silver filament. The front is some black spray paint (I didn't have any silver paint). Again this is @jedimatt42's design, I just added the TI logo to the file and printed it. This was printed at .2 layer height so it is a little rough if you zoom in, but looks better in person. Unfortunately my 32k card now appears to be toasted. A couple of the connector pins rolled while connecting it to the console. I fixed the pins but it fails memory testing now. I wonder if I fried a chip that I can replace? 6 Quote Link to comment Share on other sites More sharing options...

I recently fried my 32K sidecar by applying 9V. I replaced all 4 chips. They are very common ones. You can use 74HCT types (not 74HC) or 74LS types. Those and any 62256 Static RAM chip. One source for all that is Unicorn Electronics. 3 Quote Link to comment Share on other sites More sharing options...

Thanks for the info on the chips. Unicorn seems like a good place to find all of them. Only issue is the $30 min order. These chips come to about $5.
