One of these wasn't an M9202 but an M920. What's the difference?

No, there should be a top cover on the RK05. You can
run the drive
without it (e.g. for servicing), but it's best to keep as much dust
off the heads as possible.
I've had time for a closer look at this. The insides are pretty
dusty. I think it has been sitting around without a cover for some
time. One part looks like it had a filter over it but it decayed and
only left a bit around the edge.
Those 4 boards are the controller for the RK05. They
fit into a
special 4-slot backplane, as does the white ribbon cable from the
RK05. What's in the slot _behind_ the M7257? There should be a
terminator (either an M9302 or an M930) there.
I don't see anything behind the M7257. Didn't see anything with a
M9302 or M930 label. Please don't tell me I'm going to have to find
one somewhere. :-(
