OK, after my stupid error, I got another KA630-AA and put it
in the right slot of the H9278-A backplane. The uVAX goes
through the power on self test, and drops into ODT. I then
do the procedure in the Emulex manual to load the diagnostic
into VAX memory, but it doesn't work. line 10 is E/P/W
2000146A and I am supposed to see 400, but I get a 200
instead and nothing changed at location 80.
Is there any possibility there is an error in the manual?
(I have the very vague recollection that 40 years ago I
couldn't get this to work, and plugged the QD21 into and
LSI-11 system instead.
Is there any jumper that would be needed for DMA (NPG) to
work properly on a H9278A that was originally on an LSI-11
system for it to work on a uVAX-II?
I am pretty much at a loss here. I do have an MDB backplane
that did work in my original system, but I had cobbled up my
own DCOK and BUSINIT-L logic that never quite worked right.
I would have to resurrect all that to test with the MDB
backplane. (I no longer have the LSI-11.)
Thanks,
Jon
