content: After 30 years of occasionally poking at this thing I finally got it operating. Other than my physical unit and a confirming call to Systron Donner in 1990, I can find no evidence that this thing ever existed. I have been able to find manuals for later similar models, but not this one. Anyway, during a fit of internet free association browsing I ran across a guy that turned a similar counter (1038) into a clock and showed pictures of his work. I noticed he had a set of circuit boards similar to mine and in the case of one in particular, an exact match. So after a few back and forths he sent me the card. Anders, If you're on here, thanks again.

content: Congratulations on getting that counter up and running!Nixie tube instruments are interesting machines because they're from such a transitional period when test equipment was shifting from being purely analog to being digital to varying degrees. Plus the nixie displays are undeniably cool in themselves.The lack of documentation is interesting. I've had several conversations with people at work about how not everything is on the internet. Older, low production volume electronic equipment seems to fall into that category pretty frequently. I have some equipment from a number of small, long defunct Canadian manufacturers and other than the odd newspaper article in various archives sites and expired trademark registrations, there's very little out there on the companies that made them and even less on the specific pieces of equipment.

content: Welcome to the club! Congrats on getting it up and running. I have an old Systron 1039-9 waiting for me to get it packed and shipped home from CA; it seems to be another mystery box.-Pat

content: I don't have documentatin for my Electro Instruments Nixie digital voltmeter. However I had no trouble figuring out where everything is and calibrating it and even repairing it a while back. Maybe things were simpler then.Having said that, this old baby needs a new home. I'd love to see someone get it who can appreciate it. Five digits and 0.01% for dc and 0.1% for ac up to 1000 volts.

content: That's neat, those look like the bi-quinary tubes that fit in a standard 9 pin socket? I have a set of those in a clock I built about 20 years ago. They're somewhat unique in that the '1' is right at the front of the stack.

content: It's a good clubSomething special about nixie tubesHP 5327B (with external 10 MHz reference from BG7TBL GPSDO) displaying 10 MHz signal on input C from Agilent 33522B (also locked to 10 MHz reference from BG7TBL GPSDO).
