What does everyone know about the Texas Instruments TI-99/8? While it never was released officially, a few prototype units do exist and are in the hands of a few collectors. There also existed the instruction book to this model.
The TI-99/8 was to be TI's answer to the Commodore 64. I also believe Atari's 1400XL, which was to replace the short-lived 1200XL, among other things featured a built-in voice synthesizer, was to be that company's answer to the C64. The 1400XL was never released because at the time Atari executives felt the company should be committed to doing video games. The TI-99/2, another no-release, was to be a low-cost alternative to the 99/4 line, with monochrome graphics and no sound.
Among other things, while it was backwards-compatible with the 99/4(A) library, for some reason the 99/8 was not compatible with the Extended BASIC which supported the older model.
And had TI not went through all their millions in the home computer industry, we also could've seen their competitor to the Commodore Amiga, the 99/16. And heck, there was this TI computer, the Professional, that was a TI in name only, which was an IBM-compatible computer and featured an Intel chip. This could've sold better if it were to have been based on Atari's 1600XL, which, once again, is on the list of never-released computers. The 1600XL was conceived to have both the usual MOS 6502C chip as well as the Intel 80186 chip for greater DOS compatibility. By that I mean the TI Pro could've been made by TI itself and featured not only their TMS9995 chip but also the Intel 80186 chip.
Other TI computers that could've been released if the company's home computer division survived:
*TI-99/GC (TI-99 Game Console; remember Atari's XE-GS computer/console and the Tomy Pyuuta, Jr.?)
*TI-99/M (TI-99 Music; this would feature an 8-voice sound chip to rival Commodore's SID sound chip)
*TI-99/P (TI-99 Portable; with a built-in monochrome monitor)
