On Unibus, the controller is an RL11. On Qbus, it's either (I think) an
RLV11 (two-board option that requires a CD backplane) or RLV12 (single
board option that doesn't). The RL01 uses a 5-meg removable cartridge,
RL02 uses a 10 meg one. 4.3BSD supports the RL02, but not the RL01
adding support for the RL01 would be a pretty easy job, if anybody was
determined enough to make it work). The RL11, at least, is very
to other devices doing large amounts of DMA, as it has only a very small
internal buffer. I had to reduce the DMA burst on my UDA devices to get
to share a bus with them successfully. The RLV12, I seem to remember,
a full sector-worth of buffer, so shouldn't be so tricky to deal with.
