I beg to disagree. I've had the odd bad contact in the formed-pin

I suspect it's just that there's a huge variation in quality when it comes to
the formed-pin sockets - a turned-pin one is far more likely to work, but that
doesn't mean that there aren't some reliable formed-pin ones out there.
Whether it's possible to say that "manufacturer xyz is always good" is
another
matter...
Actually, 99% of probelms in old PETs are due to the
terrible IC sockets
used. I find it best to replace the lot with good turned-pin ones. That
may well cure this fault, if not, at least you know that's _not_ the
problem (nothing worst that trying to trace logic faults on a PCB with
bad connections!).
Tony, believe in me: Turned pin sockets are an unnecessary
spent money
