I have long had an interest in server tech and "technology with character" I finally took the plunge and got a DEC and I am looking for something of a similar vintage to connect it to.
I have read about VAXstations, z80 based mainframes. This seems like the kind of devices I would like to acquire and learn the workings of.
I also require a keyboard for my DEC terminal.
As this is my first post to the list, I am mostly looking for resources (UK would be preferable)

There's a submit button in the upper right, but it just emails me.
The entry field in the upper left is kind of fun - enter a valid address or location, select it from the drop-down box, and it takes you there. It also gives GPS coordinates.
This is a very cool COSMAC VIP that has been slightly modded to act as a
front-end processor for an SC/MP II processor board with a custom-built
front panel for the SC/MP as well as some interesting add-ons for the VIP
(PROM programmer, Tiny BASIC ROM card, CDP1855 math co-processor) and more.

I also produced a video to show off the setup for historical purposes:

Hello,
I tried to clone a boot drive ( on a bigger one ), using one of the scripts on nekochan.
The disk was initialized , labelled
Then formatted by the script, and cloned. The data is present if I mount it
The issue starts when I change the id and try to boot from it... this is what I get
esf read error, bad count
esf read error, bad count
no file system found for "unix".
unable to execute dksc(0,1,0)unix: media not loaded
autoboot failed
dksc(0,1,0)unix: media not loaded
>From Prom, ls gives :
dksc(0,1,8)/:
sgilabel sash symmon
esf read error, bad count
no file system found for "/".
Any suggestion is accepted.

Hello!
I recently received a HP9816 machine. The previous owner originally got the
machine without a keyboard but subsequently sourced a keyboard off ebay.
Unfortunately this keyboard was not in the best shape. One key was stuck
and when taking it apart it was evident that it has taken a bath for quite
some time. At least the electronics around the space bar were quite
affected with corrosion. Luckily this keyboard is quite simple design with
only CMOS 4XXX IC, and better yet, Tony Duell has already reverse
engineered it (together with the rest of this little machine). Thanks a lot
Tony!
But the stuck key appeared to be cause by the "plunger" (is that the
correct english word?) is slightly cracked in the corner. When the keytop
is inserted it is not sliding very well.
I have not found a method of repairing it so I am asking the community if
there are anyone that has spare "plungers" for the HP9816 keyboard.

This is the keyboard at the hpmuseum.net page:

So I had a random thought in the wee hours this morning and I leave it
to you, the cctalk braintrust, to tell me exactly how stupid this idea is:
I have a VAX-11/750, an Able QNiverter (UNIBUS->Qbus adapter), a 22-bit
Qbus backplane, and a VCB02 (QDSS) 4-bit graphics boardset.
Theory: With an appropriately modified NetBSD driver for the VCB02, such
that it provides only 18-bit addresses to the VCB02's DMA engine, I can
get X running on the VCB02 on the 11/750.
That is, the configuration is: 11/750->Unibus->QNiverter->Qbus->VCB02.
Obviously the console functionality of the VCB02 won't work since that
requires support on the VAX side of things that won't be present, but I
think everything else should work. I've browsed the technical manual
and I don't see anything that should get in the way, I'll just need to
hack up the driver appropriately.
But this is something that randomly popped into my head (I was inspired
by a research paper, "A VAX Based Data Acquisition Computer System at
the Nuclear Structure Research Laboratory" wherein a Matrox QRGB Qbus
graphics board was lashed to an 11/750 in a similar manner...
What say you all?

My flatmate has one of these. Just the small subassembly with the 2
push-buttons and a red light between them. Is this something that
would be of interest to anyone? I'm trying to persuade him to eBay it
instead of throwing it away.
We've also got the plastic covers from a few disk packs, an empty
metal chassis and a few other odds and sods. Sadly most of the machine
was binned long long ago. :-(
