Not strictly related, but this reminded me of the IDE adapter plans for
Qbus and UNIBUS that were floating around some years back.

I haven't unpacked any of the files there, so I couldn't say how
complete a solution it is. But there are circuit diagrams, and the
original authors claim to have gone the extra mile, and include patches
to get several DEC OSes running.
Then there was Brad Parker's thread on the same topic, which I'd
forgotten about:

I lost track of this as I moved cross country a couple months later. But
judging from this thread in late 2012, it moved forward considerably -

Either way an IDE interface should give you a path to using Compact

Anybody out here tried it with a MicroVAX, VAXStation etc?
That's where most other SCSI emulators fail, so I would be very
interested. (So I can finally stop making my owns ;-) )
Wait - are you making your own scsi adapters for vax/pdp? If so, can
you publish specifications?
