So I've decided to try and build up a KE11-A Extended Arithmetic Element. I
have most of the boards (although I*m missing a M234 Register dual-width
board, if anyone has one).
The main thing I'm missing at this point is a backplane. I do have a BB11
(which came out of an old piece of data acquisition gear, or something like
that) which I can wire up, but before I start on that I figured I'd ask and
see if anyone has one they would be willing to part with. (Hah-hah!)
If not, if someone does have one, even if you want to hang onto it, I'd really
appreciate good photos of the pin side of the backplane, so I have a more
detailed idea (than just the prints) on how the wiring goes.
And speaking of the prints, although there are a scanned set online, they are
pretty low-res, and some parts (e.g. the wire list, which was typical line
printer output) are hard to read as a result. So a new scan would be really,
really appreciated.
Thanks (I hope)!

I was idly browsing some old electronics magazines on archive.org and saw this
Tektronix testing system from 1972 that clearly has an 11/20 and TU-56. Just curious
as to what the piece of gear is sandwiched between the two. It sort of looks like a
paper tape reader, but for the two white buttons or whatever they are at the lower right
and the white bit at top right.
It seems to be in a DEC bezel(?) It doesn't seem to match the bespoke Tek gear at right
which looks quite different. I'm guessing it really is just a paper tape reader.

Thanks in advance.

I found myself cleaning up the shop recently, and came across some vintage circuit boards I had stashed away 20 years ago. I?m curious if anyone can shed some light on what systems they originally went to. Here?s a link to the album?more info below.

#1 Marked Aeronutronic Address Buffer D700909. Socketed transistors and test points along leading edge with ID tab visible when installed.
#2 No name or brand marking, sides have cast aluminum rails and a clever locking mechanism. Transistors are 2N-167 in clips.
#3 Marked 'Power Supply 1534 8253' 5-1-70, single-sided with edge connector.
#4 Large card 11?x10?, Burroughs logo. Date stamp of Jun 1972. Not sure if someone has robbed some of the ICs or if this was optional population.
#5 Small 3x4 card, single-sided but every hole has an unusual pressed-in and flow-soldered barrel. Relays are marked Blue Bead 26.5V. Looks early Japanese. 4 corner brackets have threads swaged-in for mounting.
Thanks,

and now the image of the classiccmp mailing list server should be back to where it was the day of the failure.
As per above, no data lost except a handfull asking if the server was up.
Greetings all,
I have a contact that has unearth a massive cache of Scientific Data Systems modules like the one pictured here in the Houston area: <https://i.imgur.com/m0l5IiB.jpg>
If anyone has a need for these modules or can identify based on that photo which SDS mainframe let me know and I'll put you in touch with the owner.
Best,
Ryan
I?m a collector in the Chicago area. Whereabouts are you located? I can rope up a car to grab some stuff.
Got any pictures of the piles?

Hi list,
is anyone aware of a LIF filesystem implementation for Linux? I'm aware
of lifutils, but i'm looking for filesystem integration either via fuse
or via in-kernel module. Haven't found anything on the internet.
Thanks
Sven
