it'll look purty next to my /400 box and my two /300 boxes. :)

ah ha!!  i knew there had to be some reason i was having trouble, i was treating
this as a "standard" QBus box, no WONDER i couldn't get it to see those dual
cards (i was doing serpentine QBus grant pathing)

yeah, that is kinda nifty, especially since this is going to be my "main" box
to run NetBSD/vax on, and i wouldn't mind putting a 4mm on it or something.

tapes are always nice local, although remote is always a possability (except
when you tape server loses it's OS disk then you're screwed *grumble grumble*)

wow, that's cool.  can't wait to finish getting OpenVMS 7.2 on the /400 so i
can put this thing back in the /500 and start hangind disks off of it!!! :)

nah, don't need the TK50 to install OpenVMS 7.3 from CD, so i just pulled the
TK50 controller and will put that back in after VMS is on this box at which
point the CMD controller goes back on the /500 as its primary SCSI controller.
(or only at this point i guess)

ok, so how about the KZQSA? is that a completely lost cause for NetBSD? should
i just get it over with and stick it in a VMS box?

and one last thing, i have an OpenVMS CD here.  it was a sorta quick hack job
to get it made in time for me to pick it up on my trip, so i don't even know
if it's good or not (the guy with the original did a dd bs=2048 of the cd and
entropy tried burning it to a CD with cdrdao, alas, he has no vax to test it
on at the moment) but here's is what happens:

>>>show dev
[snip DSSI disks]

UQSSP Disk Controller 0 (772150)

UQSSP Tape Controller 0 (774500)
-MUA2 (TU81)

the CMD card is the only thing in this box, i took the TK50 controller out, so
the CMD sees the CD-ROM drive as a tape device??  that's, uhm, well, i don't
even know what to say. :)

so i go ahead and:

(BOOT/R5:0 MUA2)


the CD-ROM "gets busy" for a while, and then stops being busy and the machine
hangs there.  now, is that:

a) a bad CD


b) the CMD doesn't like my Plextor UltraPLEX (jumped to 512 since it normally
is slung off my sparc20)
