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.
