V > V-MARC > 88a   


This computer was probably intended for holding OEM programs thanks to its 8 cartridge slots. Cartridges could be ROM, for programs, or RAM to store data.

The internal O.S. allowed for management of these cartridges, running programs or copying data from one cartridge to another. The content of a cartridge could be sent through the serial interface.

The machine could be powered by either an AC adaptor or an internal NiCd battery.

A V-Marc II was also sold with same features but probably had more RAM.

We need more info about this computer ! If you designed, used, or have more info about this system, please send us pictures or anything you might find useful.
Please consider donating your old computer / videogame system to or one of our partners from anywhere in the world (Europe, America, Asia, etc.).


Does anyone know if the ROM images of this has been posted online? When I try to start mine all I get is a black display, thinking maybe the internal ROM is faulty.
