Thanks to all the knowledgeable people on this board. I have been ingesting every shred of information posted for some time now and can only wait until the day arrives when I myself may be knowing enough to contribute information to the group (intelligent and correct information). I put a ZIF socket in my '7747 and burn 10 to 20 chips every weekend in search of the mighty PROM. Anyway just a shoot out to the gurus, I look forward to reading more of your teachings.
