I had this one, so I add some information $
Speed : 0.8MHz, VRAM : None(sharing the main memory), I/O ports : Printer port, Cassette MT interface, Expansion bus(mainly used for the color extension box), Power Supply : Build-in PSU
As I mentioned, there isn’t a Video RAM, so both the micro processor and the video interface use the main memory using tricky techniques.
Its BASIC language is fully compatible with the MB-6880 BASIC Master Level II. In general, it was suitable for beginners. This PC was never a major PC, but it’s my favorite.
