The CP-400 from brazilian company Prologica is a [Tandy Color Computer](/museum/tandy-radio-shack-color-computer/) clone. It was completely compatible with [Color Computer 2](/museum/tandy-radio-shack-color-computer-2/). Prologica was indeed specialised in cloning of popular micro-computers.

CP stands for Computer Personal. Released in 1984, the CP-400 shows an original plastic case, very similar to the [Timex-Sinclair 2068](/museum/timex-sinclair-2068/)! The calculator type keyboard uses a membrane for contacts. There is a cartridge slot on the right part of the case, accessed via a moving trapdoor.

The CP-400 was released as 16 KB or 64 KB models. But heating/voltage problems on first models led to frequent RAM corruption.

The **CP-400 model II** was later released, correcting those heating/voltage problems and offering a better keyboard (pseudo mechanical) and 64 KB RAM.

When the [MSX](/museum/msx-1/) systems came in 1985/1986 (in Brazil), sales of the CP-400 started to fall down disastrously. Prológica (and other companies that had launched the TRS Color in Brazil) did not provide necessary support in software and documentation. Even though the Color Computer was successfull in U.S.A., it was difficult to find material for it in Brazil.
