anybody have one of these? I was lucky enough to find
the full manual on bitsavers, but it's still not working:(
the card came from a mv2 running vms4.7 showing two
~600meg maxtors as dub0: and dub1: but it no longer works.
(address jumpering was set to secondary loc, but changed to
primary with no other disk controllers in the system)
the led error lights all come on in operational mode, and in
diag mode (sw2-1 up) and applying a reset via sw1-1 I get:
LEDs321 after powerup or reset
NNN (the manual says these are the faults) ERROR
ONN BUFFER CONTROLLER FAILURE
NON HAC TEST FAILED
NNO EMULATION FROM FAILED
OOO DIAG COMPLETE WITHOUT ERRORS
the only odd setting is a jumper J-H which the manual says should be off.
when this jumper is removed in test mode, only LED 2 is lit (formatter
error)
More strangely, with the controller help in reset, the KA650 roms find it's
registers showin on the QBUS and report 2 RA81 (which was the working
config)
some some bu registers and protocol must be work to get that far? swapping
the
8031, removing the serial EEPROM and reseating all socketed chips made no
change.
Anyone seen this failure before? -h
