Supposedly 16 MHz at full power operation, with about one cycle per
instruction. So that sounds good, I guess.

That is correct.

So a character display rather than a bitmapped one? Interesting point. I
wonder if using talkbox and some external memory for the voice clips we
could do away with a display altogether... I would think that would
simplify some things, but perhaps seriously complicate other things...
