Do you have an RH-750 and 11/750 to test against? (My
first 11/750
ran for years with an RH750 and TU78 next to an SI-9900 w/CMI
interface for disk - when my employer closed, I was able to rescue the
CPU, but the tape drive was too large and needed 220VAC so was not
rescued).
I'm sure in the grand scheme of MASSBUS-using
systems, the 11/750 is a
thin sliver of a minority, but they were out there. Hopefully any
proper MASSBUS emulator should work without any strangeness.
I knew I forgot a system. We have an RH780 in each 11/785, so we'll be
testing against that, too.
We don't have an 11/750 in the collection, or we'd try that, too.
