These days it
would be somewhat easier as I have a good
logic analyzer I could hook up to the MC68010. (An in-circuit emulator
would be even better.)
Something like that, I do happen to have (a Northwest Instruments
"Satellite" bus analyzer that can capture and store the last 4096 bus
cycles... it was $20K when it was new, but I got to keep it when the
company doors closed. I've found it quite handy for debugging
hardware and hardware/firmware issues. I haven't fired it up in a few
years - this thread reminds me I should check it - the sampler box is
no doubt fine, I'm sure, but the "head" is an IBM 5150 PC with an
ST225 - I'm anticipating stiction issues.).
Have you looked at the Intronix Logicport analyzer? A 500 Mhz. 34-channel
USB connected unit for $389. I'm sorely tempted to pick one up.
