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.
We need more info about this console ! If you designed, used, or have more info about this system,

Coleco carts work but not all of them also can not assign 2nd fire button to joystick for games that use it so you have to use one button in keyboard and one in joystick

I owned a Bit-90 when I was child and I always remember that everytime started to program, after a few lines it showed "Out of memory". Now I understand why, it has 1KB of RAM!! Great memories of 80''.
