Subject: Help with a Bigboard I

I am attempting to resurect my Bigboard I which has been setting in my
back room
for the last two years. It was running when I put it away, but it has a problem
now. All of my power supplys are up and correct and all options are installed.

When the board is powered on the screen clears, then fills with an 
alternating pattern of :'s and 0's, which then blinks at the refresh rate. This
shows me that my video section is working but seems to indicate that PFM is not
being loaded. I checked (with a logic probe, I don't have access to a scope)
and I have all clock signals.  I have removed and reinstalled all the chips in
an attempt to check for oxidation, but no go. It worked when I put it away.

Anybody have any suggestions??
