It appears that if you want to simulate a DZV or DZQ11 on a QBUS PDP11, then you have to use the UNIBUS DZ11 instead. That's OK, except that a DZ11 has 8 lines per card where as the DZV and DZQ are only 4 lines per card. Simh won't let you say "SET DZ LINES=4". This is something of an issue because I want to set up my simh environment to exactly mimic my real hardware, and it appears that's not possible as far as the DZ goes.
Or am I missing something?? BTW, it's funny that "HELP DZ" in simh talks exclusively about the DZV11 and even says things like . The DZV11 is a 8 line terminal multiplexor. . That's totally wrong. Bob Armstrong
