[GreenKeys] Model 15 timing

[david freeman]

OK, So the clutches stop things every cycle, even thought the machine is running at max speed?
Where does the 7.42 come from? I though it was 7.5 bits?
7.00 code is just one stop bit? At max speed, How would it get back in sync when it gets out?
Manually typing with a 7.00 code machine would likely work just fine, because I'm sure I add hundreds of milliseconds to each stop bit. :)

I will look for the gear part numbers and see what I can find.
