That was my reply, glad it helped.  As has already been mentioned, you
probably want to replace the bad 8520, since it is probably breaking
something else now that you moved it.  

My guess is that the bad chip is now CIA A, which I believe is marked
"even" on the PC board.  The symptoms might be that the time-of-day
clock isn't working, or the timer.device isn't working.  Although I
imagine it's possible that the chip isn't being used in the same way as
it was in the other position, so it might not be causing any harm.
