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.
