Are the sockets "special" in any way or just hard to get non-turned pin versions these days?
Nothing special at all just standard DIP sockets, the ROM socket was 24 pin and the CPU socket 40.
I generally don't use turned pin as they cost more per socket and I've never found, at least until now, any issues with standard double wipe sockets.

Not all double wipe sockets are equal. I generally go with 3M, Amphenol or Winslow only. I don't trust any of the others.

I'm inclined to agree with your assessment...

Just for fun and because I like to post mortem things, I pulled pin 1 (The collapsed one) out of the 40 pin socket:

It's on the left and compared to a good one. Definitely a sign of inferior materials IMHO so I need to either start using turned pin sockets or being a bit more selective about the sockets I buy.
