    text: 'CPU: MB68B09 and MB68B09E. It was 2 CPU system architecture. MB68B09E takes charge of graphics processing. Each system has 64KB address space, and it was expanded by MMU(Memory Mapping Unit) and Bank $ system. Both CPU clocks are 2MHz. ROM area is 31KB for F-BASIC version 3.0 and 1KB for Bootstrap.'

    text: FM77 L4 is a variation of FM-77. The machine is pre-installed "400 Line set II". "400 Line set II" enables 640x400 resoluition graphics(it was only monochrome.. :-( ) and 16 color(digital RGB''s 8 color plus high intensity channel) text video. 640x400 resolution enables good Kanji display, because each Kanji consists of 16x16 dots.

      Some deductions from the pic:

      The keyboard arrangement (10 function keys) says this is a xt level machine, 8088 or 8086 cpu, but the japanesse brand makes more probable a v20 or v30 from nec.

      The screen shows the wordstar Wordprocessor, (a quite old soft typical on old computers) this strenghts the pc-clone theory.
