BIT‑90

This is an obscure and rare system, compatible with Colecovision cartridges, just like the Coleco Adam computer. Apparently BIT Corporation was involved in the development of the Colecovision project. So this system might not be an outlaw project after all.

This is an obscure and rare system, compatible with Colecovision cartridges, just like the Coleco Adam computer. Apparently BIT Corporation was involved in the development of the Colecovision project. So this system might not be an outlaw project after all.

This computer had a full rubber keyboard, a bit like the ZX-Spectrum.
Basic instructions and graphic symbols were accessed through combinations of "function" keys such as CTRL, BASIC, FCTN and a special symbol key.

The BIT-90 could display 16 colors and 32 sprites, with a high resolution of 256 x 192 pixels.

Like its little brother, the BIT-60, the BIT 90 could accept Colecovision cartridges and Atari 2600 cartridges directly through a special interface.

The BIT-90 bears a striking resemblance to the Sega SC-3000 computer. It's not compatible, but shares some things in common.
The main point in common is that they are both designed around the powerful Texas-Instruments Video Display Processor TMS-9929A, which was revolutionary for the time.
Many systems used it, which explains the general feeling of using it:
Colecovision, Creativision, MSX computers, Sega SG-1000, Sega-SC3000, Tomy Tutor, Casio PV-1000/2000, etc.
Not to mention the TI-99/4 which of course was the first to use that VDP.

The BIT-90, like the BIT-60, appears to have been available in several colors, at least one white and one gray.

Perhaps due to legal issues, this computer didn't last long.
