2) What if the CPU is soldered to the board?
Must I desolder it entirely, or just certain pins?
I'm not sure if anyone else has replied to this...
You would be very well advised to desolder it entirely. The first time
the emulator does something that the CPU wouldn't, you could fry the
CPU. Even if the emulator just blocks certain signals, this could
affect what the CPU does next, or when it does it.
Oh, and when you put the CPU back, put it in a socket. In fact, put the
socket in first and plug the emulator into it; then don't remove the
socket when you return the CPU to service.
