Hey all;

I'm working on repairing a Heath weather computer.

Personally, I always suspect 4066's, and as for op-amps I always suspect
324's

If things are getting hot, then are you sure that the supplies are present
and correct and that nothing is shorted. If the opamps are getting hot, then
it's a possibility they're drawing a lot of current, and that will affect
the operation of the entire unit.
