The DR11s were a series of parallel interfaces for the UNIBUS. Some used DMA, others were programmed I/O.
They included:
- DR11-A: programmed I/O, dual card (in quad SPC slot)
- DR11-B: DMA, 4-slot system unit
- DR11-C: quad single-board replacement for the DR11-A
- DR11-K: hex board with similar functionality to the DR11-C, more robust user device interface
- DR11-L: double input-only
- DR11-M: double output-only
- DR11-W: hex single-board replacement for the DR11-B
