Same problem on the PET's we used to use, replaced the sockets with turned
pin types and all the problems were solved.

Ooops, I missed a footnote. What I meant to say was :
Sure. Acutally, I only use turned-pin sockets
now, the extra cost is well
worth the lack of stress caused by intermittant connections [1].
[1] My Whitechapel MG1 came with nice turned-pin sockets for all the
'expensive stuff' (32016CPU, MMU, FPU, etc) but had the EPROMs in cheap
sockets. I had numerous problems due to bad connections at the latter. I
cut out the old sockets (the sockets were junk, the PCB valuable..) then
soldered turned-pin ones in place of them. And had no more problems.
