The file needs to reside on the EPROM it's testing, but that's a waste of time. The "Port" command PTTEST$ can verify the checksum of any EPROM.

From the HP-71B Compendium, here's the EPROM manual.

And here's the programmer manual.

Found this in the manual and tried it but it doesn't give 00000.

Programs I've tested seem to work though. Maybe the 32k test in a 64k EPROM is related (unless PTTEST$ is module independent)?

I will keep tinkering - thanks all for your helpful information and tips :-)
