Re: I found it !. A very sorry looking MK14
Expanding on your own idea, do you have access to other micro toys such as an Arduino Mega? If you removed the SC/MP and connected a Mega to the CPU socket with a header you could write sketches to put any combination of address or scanned address range and RD or WD on the buses at any human-visible speed or static state you like, in order to see what is going on.
