I suspected thay'd been "fixed", but I don't think it's a
malfunction. All three sets came from the same company and all three
write to disks with the notch open.
Weird.

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.
Uhh, I have a couple of Qbus cards by MDA that I've never identified.
Got pics? 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!
