     The main concern would be decline in voltage rating of the Power
Supply's large input capacitors and, perhaps, dust/corrosion leading to bad
connections on Slot cards.

     A pretty good approach is to jot down the location of each Slot card.
With power OFF, remove all of the cards except the Drive Controller (Slot 6)
and Language Card (Slot 0). Then, pull and reinsert the two remaining cards,
being careful to line up the card contacts with Slot contacts.

     Disconnect and clean the Power Supply cable connector (e.g. with an
alcohol swab) and reconnect it. This is a good time to clean the edge
connectors of the other cards.

     Scootch-up and re-socket the 6502 and all of the ROM IC's.

     Five years is not an extremely long time for a power supply to be
inactive. I've used supplies pulled from equipment idled for longer than that
with no problem.

     So, my inclination would be to power ON the system with just the two
Slot cards mentioned earlier-- i.e. a setup which does not place a very heavy
load on the Power Supply. If it boots and runs stuff okay, play some games,
etc. for a few hours (or let it sit powered ON) to give the Power Supply
capacitors time to 're-form'.

     Later, turn OFF the computer and put the other cards into their correct
Slots.
