Notes:
Note some ROMs are mid-way between position 1 and 2 so 12 is used as the location.
M60002-0118P - Mitsubishi DIP42 custom chip. On the bootleg this chip
is replaced by a plug-in daughterboard containing a
few logic chips or integrated directly onto the PCB using logic chips.
There is a 6MHz clock input on pin 4.
MN41128 - Panasonic MN41128 128kx1 NMOS DRAM (total=320kx8 video RAM)
6116 - 2kx8 SRAM
JP8,6,4,2 - Solder-blob jumper, open
JP7,5,3,1 - Solder-blob jumper, shorted
CN3 - 4-pin power connector joining to bottom board
