Naja
This is a brasilian Tandy TRS-80 Model III compatible system.
It didn't sell well as the CP-500 was a too popular TRS-80 compatible system in Brazil.
In 1985, a new model named Naja 800 was marketed. It had a 14 Kb EPROM, 128 Kb RAM, built-in monitor, 70 keys keyboard with numeric keypad and a hard-disk.
