For RX50? On standard PDP11s, those used an MSCP

I suppose you could on a Pro, since that had its own particularly disgusting junk
controller. But I haven't seen RX50 formatting there. My impression was that they
came factory formatted, with the DEC-specific 10 sector per track format.
Acch. Bad memory cells. This actually was discussed back in 2002.
Some of the correspondents in that discussion are also denizens of this
mailing list, may recall I made the same mistake back then:
The diagnostic was/is:
BL-FN7AP-MC CZFNAP0 M-11 FORMTR RX50
So, just to verify, I fired up my 11/23 (which hasn't been on in YEARS),
which came right up, and inserted the floppy and booted it:
It formats:
RD51, RD52, RD53 on an RQDX1 or RQDX2
RD51, RD52, RD53, RD54, RD31, RD32, RX33 on an RQDDX2
Sorry for the confusion.
