This is getting to be a real pain...
Sometimes it boots, most times it won't. Usual response is I say
b du
or
b du0
It hits the disk twice, and halts at 050110. I have run the RA down all
it's diags in the manual, no faults. Same for when it boots. The UDA50
does running lights too. Doesn't matter if I use A or B. Only difference
there is A lights up sometimes and B doesn't. Cables look fine. What's
going on? Does it just hate me?
Also, when RSTS/E does come up, it sometimes traps to 4.
Timeout/sysfail vector. Something says this drive is going...

Time to get down to basics: what boards are in this system? How

And we're off!
Every little bit I can come up with.
The system is in two cabinets. Two BA11s.
I have an RA81 for the boot drive, two TU58s in the main cabinet, the
console terminal (A Wyse 30 for now), and a real funny plug in the system
case. 3 rows of wires in a printer-style plug. LP11?
BA11 #1:
This is the system box, BTW. The one whose power cord I hacked up.
The DEC power cord is 120VAC, 1 phase, etc etc. But it has a sideways
pin. So I whacked the end off a PC cable, soldered the appropriate pin to
the appropriate wire, and plugged her in. It worked.
The power controller plug was too wierd to mess with.

RSTS/E is *extremely* picky about configuration
details. If some boards have been pulled and/or added without
carefully following the rules about ordering CSR's and vectors, it's
not surprising that RSTS/E falls and can't get up.
Not even booting? And when it does boot, I get
LP0: device not interrupting - disabled
or something like that

1. You've got two RH11's in the system, but
(as far as I can tell)
you've got no Massbus peripherals. Why not pull the RH11 system units?
Okay. I'd like to trim this down to one cabinet anyway.
2. Why is there no Unibus terminator at the end of the bus? (Or
did you just leave it out?)
Oh, crap. There's the problem?
3. Are the M9300's sitting in RH11 system units?
Just looking
at your list above, I can't see why they'd be in the middle of the
Unibus at all. M9300's are terminators, and unless there's a very
special reason, they generally are only at the end of the bus.
Not sure, I stuck one on the end of the bus - everything started working!
Generally, I think it'd be wise to pull all the unused cruft (esp RH11's!)
and get the entire system in one box.
"Not Interrupting" to me often indicates a problem with interrupt
continuity. And if the interrupts aren't getting through, it's
extremely surprising that any DMA to your RA81's is being done
at all...
Now it didn't.
Apparently, someone moved some terminators around. Looks fine now!
Tim.
