   Thanks Paul.. Yes, the card is merely a "firmware" card.  It does not run
any hardware diagnostics, just software diags.  Obviously if the card comes up,
then the slots and power are working.

  I used to use the Frankln Ace 100 tests that I got as a dealer to test the
memory of the Apple II's.  It loaded into the first 4 bytes (it said) and it
was very accurate, and caught every problem.  Apple's built-in diagnostics on
the //e was highly innacurate.  It would come up with a different bad memory
chip everytime.
