IBM makes a box called a DACU which is a Channel to Unibus
converter, even has a little DD11-CK in it (!and! they put
the NPR jumpers on dipswitches you can just reach...genius!)
You didn't mention why you needed this, of course this may
do you no good. A popular use of the DACU is plugging in an
Interlan ethernet board to use WiscNet/TCP on (we do this
here at BU on our 3090.)

Years ago I believe DEC made such a beast called a DX11-??
(NO, that's *not* a floppy.) I have no idea if it is still
a product or still works.

If you're just after data transfer (is the UNIBUS part of the
VAX and the Channel part of the IBM system? Are you trying to
plug an RA81 into an IBM system? Are you trying to plug a 3380
into a VAX?) you might consider WiscNet. (This isn't as strange
as it sounds, didn't the DEC20 line have the ability to plug in
IBM channel disks/tapes? That would be the converse of the DACU.)
