They are certainly used with the 11/35 and 11/40. Also with the 11/05
and 11/10, I think
the 11/20 has a slot for them (that's what the labels in the etch of a
genuine KM11 seem
to be for) and the 11/45. Possibly other Unibus processors

AFAIK they are not used with RK05 drives, but are used with both types of Unibus
controller for same (RK11-C and RK11-D). And the RK11 of course.

Possibly other things, but those are the ones I've come across.

Pity you're not in the UK. I have a spare RX02 that I don't really
need... I don't
want to strip it for parts but I could be convince to part with the
complete thing.
