I have a set of five RX50 floppies which contain various service tests. I
have not yet discovered what machine/CPU these work upon. Could anybody
point me in the direction of how to interpret the seven-character part
numbers? All have a copyright date of 1983. They are as follows:
CZUFDB1 (disk part # BL-T540B-M1 "USER TESTS")
CZXD1B1 (disk part # BL-T541B-M1 "FIELD SERVICE TESTS 1")
CZXD2B0 (disk part # BL-T542B-MC "FIELD SERVICE TESTS 2")
CZXD3B0 (disk part # BL-T565B-MC "FIELD SERVICE TESTS 3")
CZXD4B0 (disk part # BL-T583B-MC "FIELD SERVICE TESTS 4")
Are these some version of XXDP? They came with the MVII and MicroPDP-11/73
systems that I got as part of The Great Haul back in July 1998, but there
is no indication who they go to.
I stumbled across something about deciphering those CZX-type numbers a
while back but did not retain the URL (naturally, now that I need to use it).
