I think I'll slightly disagree with you here.
While all you say is essentially true, the DLV11 is a tremendour burden on
the system compared to the DHV11. So if you actually want to run serial
connections to a machine, keep the DHV11, and don't use the console more
than absolutely neccesary.
Big difference between DMA and interrupts you know...

Thanks for your reply. I guess I'm okay with power even if I leave in
the DHV11 as it seems my BA11-N has been upgraded to a H7861 power
Unless you need the IO I'd pull it anyway. The system will run cooler
and I doubt you have need for the lines. DHV11 is a MUX and you need
the chassis kit to break out all the serial lines. Most OSs for PDP11
don't use it (system build time option) and the DLV11J is easier to use
and program. The DHV11 cannot be used for a console either.
