Right, at first I thought it might be a simple custom CPU of some sort,
but looking at the schematics (and the *very* detailed explanations in
the service manual) made it clear that it's basically a huge state
machine for parsing command text.
I find that interesting that it would not be considered a CPU.
After all, that is all a CPU does. It would seem that the only
difference was that most CPUs encrypt the instructions.
It sure sounds like a CPU to me.
It is a state machine that executes based on decoding
input.
I'm not sure that the input has to be some special binary
code and can't be directly decoded text to qualify as
a CPU.
