Got the EEPROMS desoldered from the board via the destructive method-boards are in prime condition for a pair of PLCC32 sockets now. Even though I have another PCM to use, I figure if I'm going to be flashing the thing I ought to go ahead and socket at least one PCM. I've got some old ISA cards with appropriate sockets, so tomarrow is the "let's be very careful" desoldering day.
Now, the flash chips that were in my boards were not marked for speed-do I need to get 150nS units? 200nS? 100nS?
