I have similar troubles with the 2088 board.  When it occurs, I pull off
the lid and reseat the board.  I fhtat fails, I move on to flex the
board and push all the socketed ICs home.  Serious failure mode requires
removing the board and prising up all the ICs and researing them.
I had to go through phase one the other day after I carted the 2000
around in the car - once where I took it, and once when I got back.  It
will run for months w/o touching normally.

Tinned sockets and tinned IC leads are a certain recipe for delayed
disaster (tin oxide is an insulator in this context, and is very tough).
