I'm really going to be the MeterMeister if I ever get all of the damned things up and running!
Scored a NOS weapon grade keyboard from local computer warehouse for $10, the legendary buckling spring keyboard.
The seller let it go since he claimed its no longer can be used at today's laptop anymore , but at that price as it's "branded".
PS : Anyone know how to clean the heavily tarnished 5 pins of the DIN connector without destroying the plastic housing ? (photo attached)

I would probably go with a very lightly abrasive paste like Simchrome or Brasso or toothpaste perhaps inside a piece of just slightly larger insulation - placed over the pin (one at a time) and spun by hand - then a really good clean with IPA.
And after that, I would verify the cleaning action by running a 4 wire milliOhms measurement across all pins of socket/plug connection. For this solder the leads from the DMM to the respective solder tabs on the plug, respectively socket. Then compare your measurement with the data sheet - which does not give any mOhms contact info.
Therefore some of my measurement results on an old and well stored 5 pin DIN connector:
Contact resistance after years of storage (slight oxidation is visible): 35 mOhm
Contact resistance after cleaning with "Kontakt 60" (a popular deoxit fluid in Germany): 7.6 mOhm.
There you go.

Damn, how did you know I measure those pins with 4 wires at sub miliohms resolution ?
I couldn't resist and bought some Nixie tubes from Dalibor Farny to build my own Nixie clock. He creates gorgeous new Nixie tubes. The packet arrived today:

Well as long as you enjoy them as art
There are more expensive new-old-stock Nixie tubes on eBay, but you can't be sure of the quality.

I plan to use some antique big wooden clock (sold broken on eBay) to create a steampunk like clock, and two digits on each side fits perfectly.

That's a great idea, Frank. I like the analog and digital combination. That clock is perfect for it. Looking forward to seeing yours with those big Nixies.
