CP-200

The CP-200 and CP-200S computers were Brazilian clones of the Sinclair ZX81.

However, to compete with the original model and local ZX81 clones, CP-200 models featured several enhancements.

The larger case housed the power supply unit and a slightly better rubber keyboard. Basic versions had 16 KB of RAM as well as a joystick interface cabled in parallel with some keyboard keys. The BASIC interpreter also had some improvements and additional commands.

The CP-200 also had one very unique characteristic being that the video display was inverted (white on black instead of black on white for the ZX-81). Any key pressed on the keyboard generated a "beep" sound coming from the buzzer (his only function).

The bus connector wasn't strictly Sinclair compatible (pinout was different), but an adaptor card (?) allowed all Sinclair and third companies peripherals to be used with both CP-200 models.

The CP-200s was the same computer but with a redesigned motherboard in a new smaller (hence the "s"?) plastic case. The goal was maybe to reduce the production costs.

I had one and experimented a lot with it. Its side connector does not follow the Sinclair pinout, so you cannot plug standard Sinclair peripherals to it. I had to build a re-layout board just to attach a ZX Printer to it, and it workerd flawlessly. I don't know if the CP-200S also has this characteristic...
