Notes about the board:

Ram is 2x 6264 (near Z80) and 1x 6264 near UM6845. Xtal is verified 16.000MHz,
I can also see another special chip . PHILKO PK8801. chip looks about the same as a
TMS3615 (though i have no idea what the chip actually is). its located next to the
prom, the 2x 256k roms, and the 1x 6264 ram.
Dip SW is 1 x 8-position

on the PCB is an empty socket. written next to the socket is 68705P3. "oh no" you
say..... well, its unpopulated, so maybe it was never used?
