Slot 3 is SPC; you *must* put the two main CPU cards in the rightmost two
slots.
First step will be to remove everything from the
backplane and
vacuum it out...
When you've removed all the disintegrated
foam-that-used-to-be-front-panel-filter, you might want to replace it with
something less prone to aging. I found the synthetic fibrous filter
material sold for cooker hoods (over-the-stove extractor fans) works very
well, and you can tear it into half thickness for lighter duty.
