  <!-- based on information provided by Werner Kai's machine with serial 100158
       CPU: Sharp LH0080A Z80A-CPU-D
       PSG: Yamaha YM2149F
       There seem to be engine-like chips on the mobo:
       - TCX-2001
       - TCX-2002
       PPI: could be the TCX-1009?
       There is 2kB SRAM on the mobo.

       Reverse engineering by Arjen Zeilemaker and GuvyeR800/BiFi:
       0x7FFF in slot 3-3 is a control register:
       - bit 7: COPY button status (0 is pressed), button is located left of
                the STOP button on the keyboard
       - bit 5/6: switch ROM/SRAM in page 2
       - bit 0/1: ROM segment select in page 2 (4 16kB pages)
       the rest of page 1 is the RS-232C ROM
