The **CP-200** and **CP-200S** computers were Brazilian clones of the Sinclair [ZX81](/museum/sinclair-zx-81/).
|
|
|
|
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.
