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.

This response might be a little late but yes, it is hardware-compatible with the TRS-80. I used to use authentic Radio Shack 5 1/4"disk drives connected to a Naja. I don''t remember if it needed an add-on board$ probably it did, though.

I have one model of this, an I would like to know if this model is compatible in hardware with the TRS, I mean the disk drive.
