this one seems similar to (but not identical to)
the crospang.c hardware from F2 system
todo: check clocks, refresh rate, audio balance
add dipswitches
todo: refresh rate & audio balance
verify dipswitches - difficulty & unknown dips
verify clocks for Z80 & OKI6295
OSC on the PCB are 12MHz, 14.31818MHz & 4.096MHz
