We have just about everything short of the TI 99.

Which type of TI-99 are you looking for? There were several.

TI-99/4: Chicklet keyboard and produced in 1979-1980.

TI-99/4A: Standard 48-key keyboard and improved video processor, black case, produced until 1983.

TI-99/4A: Standard 48-key keyboard and improved video processor, cream case, produced until 1984 in two variants: v2.0 O/S and v2.2 O/S. Later versions also had an improved motherboard, known as the QI.

TI-99/8: Only 150 of these were produced, in two motherboard versions. All are prototypes. I own one of these and at least one of each of the above listed types.

TI-99/2: Only a few prototypes of this one survive. Never made it into series production.

TI-99/5: Only a few prototypes of this one exist, but it is pretty much a QI /4A with an integrated Hex-Bus interface.

I have seen both of these, but I do not have them. I do have schematics for another prototype variant, the TI-99/4B, also known as the "WAXWING." The set I have is missing one of the nine schematic pages though. . .

Most of the available documentation for these variants is up on the WHTECH FTP site.
