This japanese computer seems quite powerful. The main board is located into the main case, under the monitor.
Inside this main case there are 6 expansion slots which is quite enough ! Thus a lot of expansion boards were available (disk, printers, 8088, Z80 boards, etc).
An interesting feature is that there's a little trap-door on the keyboard which reveals some cool control switches : a power switch, a text mode switch (80 / 40 columns), a reset button and volume control knob. Quite useful !

@Knight (Australia), I may be late to the party, but if you still have your Dad''s old Hitachi MB-6890 Peach personal computer, would you consider selling it?
I used to own one and left it at my parent''s house for safe keeping with a rare mainframe monitor, then my parents threw it and my rare mainframe monitor out along with some of their old furniture and defunct electronics for collection by their town council without asking for my permission or giving me a chance to arrange to transport it back to my home. The Peach and rare mainframe monitor I had were still fully functional.
If you still have the Hitachi Peach, please $ me a line at neilrued@mail2Engineer.com with the asking price and postage charge to Victoria? If you don''t have one, would you happen to know of anyone else who may still own one?
A note on the PSU - in Australia, you needed to use a power converter to adapt to 240v which weighed a ton!
Another fun part was if you didnâ€™t boot up in the right way your floppy drive would not be initialised meaning you needed to save your work to tape and then restart and read the file back off tape then save to disk!
