It used to be a fairly common trick to solder an eprom into a machine tool socket to make a more durable eprom... the pins will insert into a socket more easily, and they won't bend.
Make sure that there isn't an insert pin type socket in the circuit card. -Chuck Harris Mark Sims wrote: > > I am now fairly sure that the issues with my 4060 are due to a bad EPROM > image or some other problem with the CPU > card.
