Description
The ML-G30 Model 1 is a very professional MSX2 computer with a separate keyboard and many connectors. It has been released in 2 different colors (white and black).
This machine has only 1 built-in disk drive, but there are locations to add a second disk drive and an internal RS-232C interface (that will occupy one of the internal slots).
The back of the computer has a RS-232C switch that is inoperational as long as the interface is not added. The panel with the sound and video connectors will be different if you install the ML-35AV Audio-Video interface with superimposing, digitizing and Telop capacities.
