the strict answer to your question is "keeping the shelves from being empty".
At one time, old Sun gear was a great gateway to learning "real" Unix and a
foot
in the door for a "real" job. It's been far, far less true for coming
up on 10 years.
And then, around 4 years ago, give or take, if the job postings said "Solaris
experience required", it was Solaris 10 or nothing, something you can't do
with SPARC hardware from the 1980s.
I've turned down more free Sun hardware in the past 2 years than I've
kept. It's
still elegant, and it still runs DNS and web servers, and plenty of
other things,
but I personally don't care to spend that much on electricity for those sorts
of services at the bandwidths I require - an old laptop running Linux can do
everything I "need" at home in the way of services and suck up 90W or less.
I also have VAXen that I only turn on for special occasions - too hungry to
leave powered on all the time like we used to do back in the day. Of course,
in the winter, it's "electric heat", so no harm there, but it's summer
up here
now, so most of that stuff stays off except for a few hours here and there.

I run a reasonably recent 8-core Xeon as my primary server. I don't get
that much traffic, it's just more convenient to have a machine that I can
run heavy compute loads on from remote locations. I have a dual P3 as a
secondary DNS server.
I'm set to acquire a few more classic systems in the near term, though.
If any of them can be run 24/7 without breaking the bank, I'll probably
change my primary public-facing services to them, partly for the "fun"
factor (none of the sites I host get enough traffic to justify anything
near an 8-core Xeon) and also because something like OpenVMS on an Alpha
is a much less likely target for random attacks by script kiddies.

single internal SCSI HD, made it up to two BA350's that were mostly
full, and now has dual 3-drive SCA JBOD boxes. It also has 4mm DAT
and DLT tape drives (in the past it's had 8mm and DLT tape libraries).
The XP1000 has plenty of CPU power, RAM, and disk space for RDB and
WASD, but the configuration sucks power like crazy. Still I
seriously miss having a VMS server online, and am considering moving
it back to an AlphaStation 4/233.

I run big FPGA builds on my server, so I can benefit from pretty

parallelized very well, so I benefit more from increased clock

20% of the build. Plus, I can run multiple ones in parallel when
that's necessary.
The web/DNS/mail/file server parts of it could probably be pretty
easily handled by a 68k running NetBSD, but I already have this
running for compute tasks and it barely even registers the server
tasks, plus it has an OK SAS controller so I can use nicer disks
once I can afford them.

Alternatively, Simh simulates a uVAX 3900 faster than my actual 3900

you're not focused on having the actual iron running and have spare
cycles on a machine (on an early Opteron, I'll testify that it takes
up pretty much a whole CPU by itself, even at idle, but you can
always renice it down).

New subject: KS10 console processor (8080) firmware
Anyone happen to have access or know of an archive for the
DEC KS10 console (M8616E) firmware? The board runs an 8080A
and the firmware resides in four EPROMs as shown on pages 24-40
of the schematic:
http://bitsavers.trailing-edge.com/pdf/dec/pdp10/KS10/MP00540_KS10_MaintSch…
If a board is available for loan, sale, trade, etc that would
also work.

I don't know where I put my ROM images, but centuries ago I disassembled
them into something which would build to the same binaries:
/pub/pdp10/ks10/csl52.asm (the source)
/pub/pdp10/ks10/mcs85.inc (TASM/MASM macros to build 8080A code)
That's for V5.2 of the CSL firmware, which is the newest one I know of
but maybe there's something newer.
