                        The chip is pin-compatible with Motorola MC68705U3, Motorola MC6805U2
                        and Hitachi HD6805U1. The 4k MC68705U3 dump in MAME is from a bootleg PCB.
 
+Note from Guru: The bootleg 4k MCU dump was written to a genuine
+Motorola MC68705U3 microcontroller and tested on the original Alpha
+Denshi Kyros no Yakata PCB and works. Since the bootleg PCB is
+visually the same this suggests the bootleggers copied the PCB 1:1
+including the HD6805U1 MCU data then adapted it for the 68705U3 with
+minimal changes.
