Thanks for the special TEA member deals, zucca. :-+

Yeah, those cables are really pricey. Anyone know of a more economical source for two-slot triax cables or adapters? Pomona makes one (4725) with alligator/crocodile clips on the other end, which looks good for general bench use, but they're pricey too (over $100 each).

Pomona has a triax-to-BNC adapter (5090), but it shorts the outer shield to the inner one.

I have a K220 and a K614, both of which use the old two-lug panel connectors.

Sounds like par for the course around here. ;D

Shhh, don't say stuff like that. It increases the probability of the opposite occurring.

Quite right. Now I'm going to have to get my own back; consider it aversion therapy.

These aren't my pictures, but I did see them - and you might be able to see them on the 15th and 16th September, https://www.eevblog.com/forum/metrology/measuring-voltage-conrad-hoffmann-style-with-a-weston-cell/msg1631129/#msg1631129

The first is modern, the second is from 1962 but has better ergonomics than modern DSOs and doesn't contain any digital ICs - the digital logic uses discrete transistors.

That first one... it looks like something from a Star Trek movie. But that 567... it looks like something from The Outer Limits. Damn, that gives me serious wood. ;)

Acorn System series machines were pretty top notch. I found a System 3 in a skip at university and nursed it back to health. Had 6809 FLEX manuals and disks in the skip with it. Had rained all night but fortunately was all saved by a well placed door. Was like a System 1 but eurocard format. Basically a rack mounted Acorn Atom.  I think it is still in my parents' loft. I don't remember selling or trashing it. There are lots of vintage computer bits up there. Probably should sort it.

Edit: there's also a VME SPARCserver and a couple of VAXstation 3100s up there too.

I dunno if this is a badge of honor, or a scarlet letter on my chest... but this was my third computer. It ran a version of CP/M, and I learned GWBASIC on it. Yes that is a 5GB Winchester drive, and up til about 5 years ago when the PSU board died of rotten caps, it would boot up and run if you tapped the side of the HDD. Yes, I still have it.

My first was a Data General all-in-one desktop with 8086 processor that ran MP-OS (A variant of CP/M). My second was a cluster of NASTEC workstations and EMP-hardened CASE2000 server, which I actually got up & running on two terminals but all applications on it were contract-dependent, so would never do anything but command-line functions. I eventually modded the Server case into my first gaming PC; a blistering 386-25 (Or was it a 386SX-40?) with a whole 2048 MB RAM and an EEGA monitor from a surplus house in the back of Computer Shopper. That came bare-chassis, and I made an enclosure for it out of aluminum sheetmetal.

Duke Nukem FTW, yo!
