The DRV11s were a series of parallel interfaces for the QBUS. Some used DMA, others were programmed I/O.

They included:

  • DRV11: identical functionality to the DR11-C, on a dual card
  • DRV11-J: 4 DRV11's on a dual card
  • DRV11-B: DMA, quad card, 18-bit DMA addresses
  • DRV11-WA: DMA, dual card, 22-bit DMA addresses

There is also a DRV11-C (M8040), but little is currently known about it.

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