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?
