I see that there is no Texas Instruments TI-99/4A computer cart covers listed. Are there any cases that will fit the cartridges without modification? Does anyone here collect the games? It was one of my first computer systems. I had the speech synthesizer and the peripheral expansion box as a kid. Within the last year or so, I bought another TI-99/4A computer system, speech synthesizer, and a compact flash device that adds 32kb ram and emulates the PEB. The best thing about it is that you can use the flash 'PEB' with a speech synthesizer without any modifications, something you couldn't do with the original system.
Although I had fond memories of the system in my youth, one thing I really didn't like, after going back so many years later, is that the graphics took so long to draw on the screen for many games. Some are like a 2400baud modem on oldskool BBS systems.
Parsec, Tunnels of Doom, Miner 2049er side-cart, all great memories!
