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.
