The DR11s were a series of parallel interfaces for the UNIBUS and QBUS. Some used DMA, others were programmed I/O. They included, for the UNIBUS:

  • DR11 (sometimes called the DR11-A): programmed I/O, quad SPC slot
  • DR11-B: DMA, 4-slot system unit
  • DR11-C: single-board replacement for the DR11-A
  • DR11-W: hex single-board replacement for the DR11-B

and for the QBUS:

  • DRV11: as for the DR11, on a dual card
  • DRV11-J: 4 DRV11's on a dual card
  • DRV11-B: DMA, quad card, 18-bit DMA addresses
  • DRV11-W: DMA, dual card, 22-bit DMA addresses

All use the same interface, except the DRV11-J, which for space reasons uses a different header on the card.
