I don't think anything will happen. I've x-rayed a ton of junk at MUCH
higher dose rates and there hasn't been any damage. My coworker's cell
phone has seen a lot of time. ; )
The Apple IIe shouldn't have any bad signs for at least 2,000 rad.
PROM takes a lot more radiation to erase than EPROM. Even EPROM is
safe at the radiation dose I gave it.
