'maincpu' (2AC6): unmapped i/o memory write to 00FA = 03 & FF
'maincpu' (0082): unmapped i/o memory write to 0024 = 06 & FF
Debug stuff:
- Start it up
- Write FF to 7D57 to see some messages
- Write 00 to 7D57 to silence it
Even though it gives an input prompt, there's no code to accept anything
Terminal settings: 8 data bits, 2 stop bits, no parity @ 9600
