has a sticker marked
Part # 04-0008
Main PCB w/ Dark-Slide
Serial# : 0115
2x Z80
There were several different designs for this, it's possible they used
different speech roms etc.
ToDo:
- work out how the cpus communicate (there's an interrupt handler in main cpu)
- clear up the speech
- inputs
- mechanical matters (camera, printer, etc)
At the moment it simply outputs all the speech strings, one after the other, then stops.
