I saw a big capacitor or a RA82 disk blowing up... Lots of black smoke which smells really foul... And I saw the interior of the unit when the DEC field technician came to repair it. An ugly mess of half-burned oil...
Of course, when the cap was replaced and the cabinet was cleaned up, the disk spun up and ran without losing a single bit :)

Hopefully not with the original PSU? ;)
No, it's original. I have at least three of them (without fans).
However, I think the last one gave up last year. I'm now running with
with fans...
The board seems to be fine without fans...it's just the PSU needs
them..
I have a little fan running on my DECserver that has an external PSU
now. It runs fine like this.
Like I said. All my experience with the DS100/200/300 are that the PSU
is the thing that eventually gives up. :-)

Usually the electrolytic capacitors of the PSU deteriorates and will
eventually cause the PSU to stop delivering the correct power to the
logic board and it will stop working.
If you want to fix it, replace the (electrolytic) capacitors and in most
cases you'll have a running DECserver good for years to come.
I'm still betting on the melted rubber being the cause of the failure in
my
decserver's PSU. ;)
If you don't want to do the replacement yourself, find a TV repair shop
in the neighbourhood and ask them to do the replacement. It won't cost
huge amounts; maybe 10-20 for the capacitors and an hours work.

Hello!
I've seen the effects of blown electrolytic capacitors. It's not
pretty. Remember that photo you showed us of a R.PI posing as a
system? It was resting on a specie of Dell Optiplex. Most of the
family is well behaved, but one member was deliberately built with
less then stellar capacitors.
Eurgh. I hate those designed-to-fail Dells. They do make great space
heaters. ;)
They all failed in less then a year.

Incidentally Dave this problem isn't your fault. I might want to
consider having those Yeti move back......
I don't think Yeti have a particularly usable capacitance

Hello!
The one I was arguing with died of a different ailment. Cascade
failure in its memory controller. But an earlier one did die from that
particular problem. It was a paired P3 (I think), although it might
have been a paired P2, but, not important.
The Yeti are doing something else. Its a holding action before the
next wave arrives. Cybermen. His cats are paying for it. With his
poker winnings.

That is also an option. ;-)

No problem. A couple of switches that might interest you:
/SYS
/IO
/RMS
err -1/sys
is different than
err -1/io
I don't remember if I ever added any other switches...

Oh. Good to know.
Being a total noob, how do I run a "proper SYSGEN"?
set /uic=[200,200]
@sysgen
I might have the wrong UIC though. Let me know if that doesn't work.
Nope. That is the correct UIC. Note, however, that depending on specifics, a SET /UIC might not do what you want. It's a rather long story, but the short of it is that it might just change your identity without changing directory under M+. But that depends on whether you are in named mode or not.
But SYSGEN.CMD lives in LB:[200,200], and a proper SYSGEN means running that thing. And on a real PDP-11, answer a bunch of questions, and wait somewhere between four and eight hours for it to complete.

At the same site you can find the the NETGEN procedure:

Have fun! :)
And if you really want to have fun, the proper manuals can be found at bitsavers. The one you want is http://bitsavers.trailing-edge.com/pdf/dec/pdp11/rsx11/RSX11Mplus_V4.x/2a/A…
