- Keyboard is a standard pc keyboard
- Sound is stereo dac-sound, plus an analog output. Details unknown.
In non-debug mode it runs for a few seconds then freezes requiring MESS
to be forceably closed. In debug mode, it can be seen that a processor
exeception occurs, although sometimes the cpu 'just stops', causing a
MESS freeze. Obviously the real machine doesn't do these things.
This system uses a number of unemulated opcodes (A0xx). Our M68000 core
mishandles this scenario, doing a random jump to nearby code. This
continues, filling up the stack, and eventually causes a total freeze.
