pixelpedant Posted November 24, 2022 Share Posted November 24, 2022 There are various TI-99/4A-adjacent computers which attract interest here. Geneve, CC-40, Tomy Tutor, TI-74, TI-990, etc. What relative of the TI-99/4A that you haven't seriously delved into yet are you tempted to explore, these days? Either via original hardware, or emulation. Or is the TI-99/4A itself enough for you? 4 Quote Link to comment Share on other sites More sharing options...
RickyDean Posted November 24, 2022 Share Posted November 24, 2022 Well , I've got ti99/4a's and Geneve's, I've always wanted to delve into the 99/8. 5 Quote Link to comment Share on other sites More sharing options...
WhataKowinkydink Posted November 24, 2022 Share Posted November 24, 2022 I still would like to get a real Geneve (even if it were a 'modern' one) not just in emulation, and as @RickyDean mentioned, the 99/8 would be cool to explore, too. 1 Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted November 24, 2022 Share Posted November 24, 2022 I suspect I am one of the worst case freaks here. I have a Dimension 4, 99/4s, 99/4As, 99/8s, a Geneve 9640, Tomy Tutors, Tomy Pyuutas, CC40s, TI74s, Powertran Cortices, a Marinchip S-9900, a TM990/189, and most of the parts to build a TI-990. I have parts to build one of Stuart's updated Cortex boards too. . . 11 Quote Link to comment Share on other sites More sharing options...
pixelpedant Posted November 25, 2022 Author Share Posted November 25, 2022 Yeah, doubtless you've got to strain the sense of the word adjacent pretty far in this context, before you find yourself wandering outside the bounds of the Fetzner Collection. 1 2 Quote Link to comment Share on other sites More sharing options...

Either via original hardware, or emulation. Or is the TI-99/4A itself enough for you? I’d like to play with a Genève one day. Or, at least, get my hand on a UCSD Pascal p-code card since I consider this a different beast than the stock 99/4a. I played with 6502 and 68000 plenty, so I want to learn about other architecture. I wouldn’t say no to an MSX/Z80 system also. 1 Quote Link to comment Share on other sites More sharing options...

8_is_enuff Posted November 25, 2022 Share Posted November 25, 2022 I'd like a Tomy Tutor. I saw one at a flea market once, but didn't get it--wish I had. I've always liked Tomy toys. 2 Quote Link to comment Share on other sites More sharing options...
pixelpedant Posted November 25, 2022 Author Share Posted November 25, 2022 Likewise. After all, in the same years when a bunch of you were driving to work at the height of the home computer boom, I was driving nowhere (but fast!) on my Tomy Turbo: But seriously, I think those things were rather exciting for about 20 seconds if you were the right age when they released (in 83 apparently). Then it became clear that they don't really *do* much of anything. Pretty exciting for those 20 seconds though. 7 1 Quote Link to comment Share on other sites More sharing options...
+retroclouds Posted November 25, 2022 Share Posted November 25, 2022 For me that is Geneve, tomy tutor, cortex and 990 systems. For non TI computers it’s MSX1 & MSX2, BBC Micro, DEC Microvax, SUN Sparcstation. Most of these systems I have (well except for 990, Microvax, Sparcstation) 2 Quote Link to comment Share on other sites More sharing options...
speccery Posted November 25, 2022 Share Posted November 25, 2022 Within the TMS9900 realm in addition to the TI-99/4A I'm interested in the Geneve, Tomy Tutor and the TI-99/2. Of course all three are based on the TMS-9995. @pnr made a FPGA version of the TI-99/2 (not sure if it's complete) and I have played with it. I find it interesting since it has a "normal" architecture: memory mapped frame buffer, no GROMs and I guess no GPL either. That architecture would be much better for BASIC. I just dug up the "TI992_Product_Specification.pdf" and indeed the memory layout is nice, no I/O devices breaking the memory map in the middle. Makes me think if I should build one myself, I recently acquired two more TMS9995 processors (still untested). Just use the existing spec and of course add color graphics 5 Quote Link to comment Share on other sites More sharing options...

I would love to find the Dimension 1, Dimension 4, 99/4B a 99/7 to study them in details. 6 Quote Link to comment Share on other sites More sharing options...

+Vorticon Posted November 26, 2022 Share Posted November 26, 2022 The CC40 is a very underappreciated computer. It's Basic is very similar to TI Basic including character definition and is very easy to use. And now that we have an SD-based drive for it, sharing programs has become practical. Not to mention the availability of a multicart that includes all the major apps and languages available for the system as well as a RAM expansion cart. I think Greg's store carries most of these. I thought these developments would spawn a renaissance for the CC40, but sadly it did not materialize... 4 Quote Link to comment Share on other sites More sharing options...

Hopefully that would happen. Sadly I don't personally have one, although I do have a TI-74 which I like and I so much want to replace that screen with a small graphics color screen... But I don't want to butcher the otherwise fine TI-74. I like its keyboard. I love the portability, but no 16-bit CPU and the one line LCD is limiting. 1 Quote Link to comment Share on other sites More sharing options...

I think that apart from the lack of an affordable storage device (now corrected), the CC-40 had the shortcoming of having an LCD screen consisting of only one line of display. When you consider the large size of the CC-40 (and the empty areas inside), the integration of a two or even four lines screen would was easily possible and would have made the CC40 the perfect machine, allowing the development of fantastic applications. My dream pocket TI computer was the CC-70, never marketed, alas... 1 Quote Link to comment Share on other sites More sharing options...

+FarmerPotato Posted November 27, 2022 Share Posted November 27, 2022 I love the CC-40 mainly because there was a time when I was forced to use it. Over a 3-week road trip vacation, my computer was the CC-40, lots of batteries, and graph paper. Later, I still used it to call BBSs. Because I had no modem on the 4A, and used it as a 4A modem relay. (PC Pursuit dialup was free at night then. Used the CC-40 for that.) So, I'm interested in getting up to date with the CC-40 and HexBus. If I had a chance, I would adopt a 990 chassis. 3 Quote Link to comment Share on other sites More sharing options...

Since the great majority of units have missing pixel rows/columns. With a screen replacement solution, the CC-40 would have everything it needs to be properly enjoyed by as many people as own one. 2 Quote Link to comment Share on other sites More sharing options...
+Vorticon Posted November 27, 2022 Share Posted November 27, 2022 One would be surprised with what can be done with a 1-line display using a little creativity. I've written a WWI air combat game on it! But I do agree that the limited screen real estate was a poor design choice. On the plus side however, the large font is very easy on the aging eyes The CC40 is the perfect companion on long flights as well where using a laptop on the cramped seats is an exercise in contortion... 1 Quote Link to comment Share on other sites More sharing options...
