Hmmm, another Cromemco board bad this way? I found the pins not only
tarnished black but corroded through on a 16KZ, usually in a group on the
same IC. The bad chips were all made by TI. Maybe there was some chemical
residue from Cromemco's wave soldering that did this? Anyway, I had to use
tweezers to remove the end narrow portion of the pins from the sockets.
