based on the Floatingyeti system; MB 6890/Hitachi Basic Master Level 3
 This Japanese computer looks pretty powerful. 
The main board is located in the main case, below the monitor.
Inside this main case there are 6 expansion slots, which is plenty! Therefore,
 many expansion boards were available (disks, printers, 8088 boards, Z80, etc.).
 One cool feature is that there's a little hatch in the keyboard that reveals some cool control switches: a power switch, a text mode switch (80/40 columns), a reset button, and a volume control knob. Japan PC with only three games (on MAME SL)
