(I''''ll write this as a message because "Add Info" does not work) MB6885 was successor of MB6881 (Basic Master Level II 2) . This machine had 256x192 graphics feature. Color display was also available with optional color-graphics adapter. These new feature was great in "Basic Master Level2 series" but not enough in Japanese market. Hitachi thought the MB-6885 as a hobby computer. But the hobby computer market was a fierce battlefield with NEC (PC-6001) , VIC-1001(Commodore) , JR-100 (Panasonic) and etc. MB-6885 was too weak for that battlefield.

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.
