Then try a command that definitely isn't going to be there $ MON NOTTHERE If the error messages are different - then at least some of the support for the undocumented classes is still there.

It enabled the monitor class Ethernet. Is that code still hidden in MONITOR? The MONITOR utility was written in PL/I at the time. Probably rewritten, right?
