BG Micro, a surplus electronics dealer I buy from sometimes, has diskettes for sale. I don't know anything about them, but thought it may be of interest. I have no affiliation other than being a customer on their mailing list.
Here is a link to the site:

I have a ton of DEC boards that I will probably never use. I sell off what
I can, when I can, but have large quantities of some and no need for them.
I have to do something and I like recycling cans and plastic, but not
computer parts. If anyone can use these or any other DEC board, feel free
to contact me off list.
I would prefer to sell in qty, but will consider all requests. If you are
parting them out and don't want them, I will reduce the price and keep the
fingers.
Thanks, Paul
Hi there.
I just acquired a board with the number M7609. It was advertised as an M630-CA which my research tells me is supposed to be 16MB. How do I tell on the board if this is 8MB or 16MB? There does not seem to be a suffix on the board that I can see.
What to look for?

Spider Robinson did a story about this, entitled ?The Time-Traveler.?
The method, while as easily-implemented now as it was then, is not pleasant.

Here's pot stirrer for a holiday Friday afternoon:
How many different protocols / methods can we collectively come up with
for how email can be transferred?
I'm primarily thinking about between servers (MTA-to-MTA). But I'm also
willing to accept servers and clients (MTA-to-MUA). Where you can /
could run at least one server yourself.
? SMTP(S)
? UUCP (rmail)
? MMDF
? X.400
? Microsoft Exchange proprietary protocol
? Novell GroupWise proprietary protocol
? Lotus (IBM) Domino proprietary protocol
? FidoNet (FTN)
? BITNET
? Direct file access - group Post Office
? Direct file access - mail spool

Hey, thanks for taking the time to provide all those details.
As you no doubt saw, our emails crossed; I had managed to work out my own
what the difference was. I'd been looking at this page:
http://corestore.org/DEC2065.htm
and saw the two backplanes, and assumed one was the EBox, and one the
MBox - wrong! But eventually I got it straight...
One some other points you covered:

Got it; makes sense.
Could an -A be upgraded to a -B by swapping the I/O backplane? (Yes, the
wiring to the I/O connectors would have to be changed too, and that might have
been too difficult.) But could the APR handle it (perhaps with one or more
board changes)?

Useful terminology to know. Do you happen to know what 'PV' stands for -
or is it just a random letter code?

Do note I said "KL10-A and the KL10-B", not 'Model A and Model B'... I
assume the APR's in the -A and -B were identical, it was just the I/O
backplane, etc which were different.
On the -PA to -PV upgrade, could the backplane really be done with some
wraps? I ask because I saw in one manual, talking about a KL10-C to -PV
upgrade, it calls for a backplane swap-out.
I've also got some open questions on the later things like the KL10-R, -PW,
and MCA25, which are not covered well in the documentation avilable in
bitsavers; do you know about the later variations?

Today I can announce that 10 original Apple 1 computers will be
displayed at VCF West, and we're working on getting more. Several of
these will be up-and-running. Original and current owners will join
early Apple employees in a panel to discuss the computers, why they were
purchased, how they were used, and what the owners plan to do in the
future. So, buy your tickets online now. :)

Does anyone here have any sort of guide on how to get QEMU working
emulating a sparc or sparc64 machine WITH networking that actually works?
I've been banging my head against zillions of guides that are dreadfully
outdated or just don't work.
