It is a really slick system. The built-in diags

suit me better. You have to power cycle the disk drawer for each floppy
you format, which is probably OK but it gives me the heebie-jeebies. :)
The RXV21 clone controller I have in my primary 11/23+ system (an MXV21
made by MDA) allows simple formatting by poking a couple values into the
right registers. It works great. A few minutes of coding would result in
a SAV program that does it for you with prompts.
Speaking of which: off-hand, how would one create a binary program under
RT11 and then save it?
Another thing that caught me short is that the
DSD-440 honors the
write-protect notch. The RX02 doesn't (or my RX02s have been modified),
so it was a little surprising when I got a write-protect error on a
scratch disk I've been using on my 11/84.
Your RX02s are broken!
