KEMITRON – Naja
Este es un sistema brasileño compatible con Tandy TRS-80 Modelo III.
No se vendió bien porque el CP-500 era un sistema compatible con TRS-80 demasiado popular en Brasil.
En 1985, se comercializó un nuevo modelo llamado Naja 800. Tenía EPROM de 14 Kb, RAM de 128 Kb, monitor integrado, teclado de 70 teclas con teclado numérico y disco duro.
