The CP 400 COLOR was launched in 1984 by Prológica, a Brazilian company which made clone versions of various computers, under the general designation of "CP" (for "Computador Pessoal" in Portuguese, "Personal Computer" in English).

The RadioShack TRS-80 Color Computer, later marketed as the Tandy Color Computer, is a series of home computers developed and sold by Tandy Corporation. Despite sharing a name with the earlier TRS-80, the Color Computer is a completely different system and a radical departure in design based on the Motorola 6809E processor rather than the Zilog Z80 of earlier models.

Kenneth (Ken) Kalish wrote many games for the TRS-80 Color Computer and Dragon 32/64 home computers in the early 1980s, including:-

The MX-1600 was an 8-bit home computer produced in Brazil by the company Dynacom in 1985. It was one of the many clone machines based on the TRS-80 Color Computer introduced during the Brazilian "Market Reserve", like the Codimex CD-6809 or Prológica CP 400 COLOR.

The VC 50 was an 8-bit home computer produced in Brazil by the company Engetécnica (later called Varix) between 1983 and 1985. It was one of the many clone machines based on the TRS-80 Color Computer introduced during the Brazilian "Market Reserve", like the Codimex CD-6809 or Prológica CP 400 COLOR.

The Color 64 was an 8-bit home computer produced in Brazil by the Rio de Janeiro company Novo Tempo / LZ Equipamentos between 1983 and 1986. It was one of the many machines based on the TRS-80 Color Computer introduced during the Brazilian "Market Reserve", like the Codimex CD-6809 or Prológica CP 400 COLOR.

The Dragon 32 and Dragon 64 are home computers that were built in the 1980s. The Dragons are very similar to the TRS-80 Color Computer, and were produced for the European market by Dragon Data, Ltd., initially in Swansea, Wales, before moving to Port Talbot, Wales (until 1984), and by Eurohard S.A. in Casar de Cáceres, Spain (from 1984 to 1987), and for the US market by Tano Corporation of New Orleans, Louisiana. The model numbers reflect the primary difference between the two machines, which have 32 and 64 kilobytes of RAM, respectively.

Microware Systems Corporation was an American software company based in Clive, Iowa, that produced the OS-9 real-time operating system.

The Codimex CD-6809 was an 8-bit home computer produced in Brazil by the company Codimex Imp.Exp. de Computadores Ltda from Porto Alegre. It was introduced in early 1983, during the Brazilian "Market Reserve" period, and based on the TRS-80 Color Computer.
