But of course they didn't have flash ROM in 1984. Had EEPROM though that required more supporting stuff onboard to program it. Some high-zoot XMS/EMS boards for PCs had EEPROMs for reconfiguring without opening the box and flipping a dozen switches or shuffling a ton of jumpers. :) Hmmm, I assume the PRAM would've had to be a bit of CMOS RAM, but how'd they fix it so the initial power on date and hours of use could survive a bit with no battery or a dead battery while the rest of the data would instantly go *poof* with the battery out??? ===== http://www.junkscience.com "All the Junk that's fit to Debunk!" __________________________________________________ Do You Yahoo!?
