Next question!
Is the CPU card you are trying to use a "ZIF Carrier" --- if so, the
next possible place to look for flakey connections is the ZIF socket
itself. Also another (less likely) possibility, is a 'bad solder'
joint on one of the ZIF socket connections. Turn the card over, and
look a individually (like each pin separately) at the solder pads. A
'Cold Solder joint will have a 'flat' vs. 'glossy' look to it. If you
find one of these, is might help to 're-flow' the solder for that
pin/joint. (This takes a steady hand, and a fine tip soldering iron ---
also, don't forget to remove the PPC chip from the ZIF while you are
reflowing the solder on the other side of the card. (I've got to look
at MY ZIF card and see if that may be my problem.)

Can anyone think of another tack to take??
