I've stuck my RX02/RXV21 into my microvax and used it. However, I prefer
the DSD880 subsystems, as they have formatting built into the front panel
and firmware. I also prefer to run RT-11 to do all the fooling around,
not VMS/Unix/RSX/RSTS,etc. If I recall, the DSD box or the SMS/Qualogy
boxes used the standard 850/851 drives. I haven't powered up the DSD
440 floppy subsystem I have, but I'll bet that does both/all three
densities.
I have some OLD 8 inch IBM drives in external boxes. Never opened them.
If you want to try one in the project, let me know, you can have one.
No idea of the model or if they are single density. I'll pop one open
if you want.

Man, I'd love to have a DSD880 setup, but nobody's offered one for
sale or trade lately.... I have a suspicion that this 3rd-party Unibus
controller does the same basic thing, and I found a reference to it
using standard 851 drives, but I can't find any more than that.
For the immediate project, I'm OK. I have some SSSD blanks, I have
RT-11, and I _think_ the 11/83 is speaking to the RXV21 correctly. I
just need to sit down with the RT-11 docs (OK, *find* them first) and
learn how to dup and verify a system disk.

The enclosure would be very welcome. The YE Data drive (a YD-180)
that I'm fooling with actually came out of an AS/400. I don't suppose
you have any controllers or the external cables for them?
We should probably take this off-list.
