[Simh] DZ11 vs DZV/DZQ11

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
