I installed a Versatec model 121 controller (C-PDP-11/DMA/18-BIT)
on my VMS 11/750.  We are not trying to use the DMA; just using it
as a standard DEC line printer.  I did remove the NPR jumper on the
backplane for the controller board per the versatec manual.  VMS sees
the versatec as a line printer and is happy to print on it; and indeed
the versatec prints what it  is told to.  BUT, the 750 will not do anything
while the versatec is printing.  It goes into a long pause.
My unibus contains (in order): the versatec, a DSD RX02 emulator, RK07, 
LPA-11KK, and a Western TC-130 tape controller.  Any ideas?
