What we are debugging there is the serial shift register and its interrupt,
the tests puts data into the shiftregister to shift it out and then checks the
value of the ICR at varying amount of cycles after that. The timing for the
4485 CIA seems to be shifted one cycle.

...the harm was done: the topic became known as "computer science"---which,
actually, is like referring to surgery as "knife science"---and it was firmly
implanted in people's minds that computing science is about machines and their
peripheral equipment.
