I also have a YF card. It came from a PDP-11/10 and was sitting in location
I put it into my NC and there were no smoke coming out anywhere...
I could access the contents but it didn't run very well. So either the CPU
is still bad or the PROM contents are bad.
Could you please direct me to your YF dumps so I could compare? Intel HEX
would be fine.
If you also have done a disassembly that would be very interesting.
