The Primo computer series was manufactured by Microkey Kftt. (Kutatási Fejlesztési Termelési Társulás), and was originaly developed to be a school computer in Hungary.
The system was sold in various memory configurations: A-32: 16K ROM 16K RAM A-48: 16K ROM 32K RAM A-64: 16K ROM 48K RAM B-64: 16K ROM 48K RAM
Other differences were:
A type did not have built-in joystick and serial ports.
B type could works togewther with the Commodore VC1541
floppy drive unit (external software had to be load for this from tape).
B type also featured a full stroke keyboard (capacitive was not a
perfect way for quick typing).
There was a colour prototype as well, called pro PRIMO.
Thanks to Viktor Varga for information and pictures.
I was an owner. The primo was a really good machine, but not for games. No colors, no professional Keyboard, but usable for working.

Looks more like a children''s toy computer than anything resembling an actual computing device. In fact, I can remember something like this that was available in stores in the 1980''s. Except the one I''m thinking of had a handle on it and ran on batteries.

Compared to the Commodore Vic-20 and Commodore 64 computers being made in the same year, this computer is just plain junk. Sorry.
