There are likely commercial products that can record and analyze logic levels. But I've seen people use microcontrollers to do that as well. Pretty much any modern microcontroller is a speed demon compared to the IEC bus. So sampling bus states and serializing to a PC for analysis should be straight forward.

For IEC, even the parallel port of a PC can do the job (that is, if you still have one).
I had written a small program for this many, many years ago (
