BIT 90

This computer had a completely rubber keyboard a bit like the ZX-Spectrum. Basic statements and graphic symbols could be accessed via 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 directly accept Colecovision cartridges, and Atari 2600 cartridges through a special interface.

The BIT-90 is also supposed to be a Sega SC-3000 clone with which it bears a striking resemblance.

The BIT-90, like the BIT-60 seems to have been available in different colored models, at least one white and one grey.
Surely due to legal problems, this computer didn't last long.
