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 :-)
As KimH mentioned, PTTEST$ and ROMTST will only pass if a checksum is stored in the EPROM, so if the test fails it doesn't necessarily mean the EPROM is bad.
