While an RK05 or RK07 drive would be really neat, I don't really have room
for something like that.
The RKV11 controller is somewhat rare (and only supports 16-bit DMA,
intended for an LSI-11) and there is no Qbus version of the RK611
controller.
Alternatively, has anyone ever tried to use a parallel
ZIP-100 on a PDP-11?
I am not aware of anyone using parallel ZIP drives on anything but a
PC parallel port. The SCSI ones work fine on pretty much any machine
with SCSI (Amiga, Macintosh...) and I know they've been used in a
PDP-11, but as you said, Qbus SCSI controllers are expensive.
