Is "metric assload" am official Department of Weights and Measures unit of measurement?

The problem with EPROMs forgetting their contents is charge leakage from the floating gates, not chip failure. I have a metric assload of EPROMs (literally thousands) of nearly every type, especially the really common ones like 2764s, if anyone needs them. -Dave

Almost every EPROM I have has been scavenged from some sort of junk board or another. 2764's and 2732's are quite common, should not be hard to find.

I'm trying to get a Plus HardCard going again. Like many the ROM has forgotten some of its bits so I want to try installing a freshly flashed one.
What's a good source for 7264s? Is it worth trying to get used ones on eBay? While I'm at it I'd like to track down a 2732 for an Apple ProFile formatting rom.
Thanks,
