Even if an EPROM has gotten corrupted, the chip itself should still be fine. Just erase and reprogram. I've yet to have a problem with doing this, it's quite rare to have a dead EPROM. 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. -Ian On Tue, May 24, 2016 at 11:22 PM, Jason Perkins via vcf-midatlantic <vcf-midatlantic@lists.vintagecomputerfederation.org> wrote:
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,
