RE: Fluke pods and 6532's

I would probably be unusual for you to get two bad chips.

Were you able to find the data sheet on the 6532? It's likely that there
are different variations that can run at different clock speeds. That
may be your problem.

Just an (educated) guess. I'm sure others here are a lot more familiar
with the specifics of the 6532.

(BTW, did the new chip run in your 6502 pod?)
