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.
