Here is my Nixie Tube equipment. An Heathkit IM-1202 Multimeter and two Frequency counter : Monsanto 100B & Philips PM 6607   :)

Never seen or heard of this beastie, interesting look. I like the number of tubes they managed to stuff in there  :).


it certainly is an interesting beasty - the modules at the top are removable and (apparently) generic counter modules model AC-4 decade counters. the HP521D (the one I have) uses the AC-4K which takes up to 120 Khz.

The valves are twin triodes with each one making up a flip-flop (or 'Binary") so the 4 flip-flops make up the counter - although it doesn't quite put out regular BCD (not sure what this counter is called).
the counter modules have a stair case output to let you make recordings on a chart recorder and decode to one of ten for the Nixie Tubes  is done by an array of Neon lamps and photo resistors.
For those who are interested, the manual for the AC-4 counters can be found here:

My only piece of Nixie equipment is a Fluke 8375A DMM.  5.5 digit, one year accuracy of .01%, input impedance up to 10 Gohm, gold-plated traces on critical boards.  I was surprised to see a flexible circuit board in a Nixie-equipped unit.  I didn't realize that flexible circuits were used that far back.  Date codes suggest that some boards have been swapped.  They vary from '72 to '84.

You shouldn't really be, flexi boards were common in auto dashboards even in the 70's.

Well there was this fella. It's big. And it tells the time. So I called it The BigTime.
Radio synch, IR remote, chimes, ambient temperature and relay output. And it was BIG.

Oh, and this one. I was going to call it "one sixth of a BigTime", but it ended up with the slightly snappier "CYCLOX" miker, instead. Serial Man-Machine Interface!

Those are very cool, Lawrence. What do the neon bulbs on the far left and right of BigTime indicate?

Far left Neon is for AM/PM indicator (over here in Europe we prefer 24 hours a day rather than two lots of 12 (!), so it's superfluous)

Far right neon indicates alarm is on/off or in snooze.

Middle two neons just mark the seconds, really, but for added cool are PWM'd to fade dim/bright/dim... ;D

Breathing neon. Cool!

On my own stuff, I use 24-hour time and yyyy-mm-dd date formats. They make more sense. The rest of the house, though, is US standard. ;)

BK Model 281, currently employed as a DC battery bank monitor.  Sorry for the crappy exposure, pretty dark in here, it's reading 13.3v.

Bell and Howell (Heathkit) DVM. The '1' digit is actually a neon bulb.

Do you have a manual? I've had one for a while that also needs going over...

Nope, no manuals, appears they are not readily available either.

some of my stuff.
A frequency-counter from HEB
and
a flexibel instrument Symetra D from METRAWATT with plugin E12 for temperature measuring with different types of heat probes. There exists another plugin which works as multimeter.
Interesting is the additional analog instrument underneath the nixies.

A recent acquisition - a little 3-1/2 digit nixie meter.  It's a United Systems Corp. 262A, made in early 1971 based on the date codes on the parts inside it.  The case is a bit rough (it seems to be covered by something that feels slightly rubberized, and it's not fared well over the 45 years since it was made - it's rather scuffed and battered).  It needs a good cleaning, but seems to work based on a quick checkout.


It's mostly discrete construction, with a few 14 pin DIPS - some Motorola ones that appear to be simple logic chips based on what I've been able to find (don't have Motorola data books of that vintage), and some that might be Fairchild, that based on their number and location seem to have something to do with driving the nixies.


A cool piece of equipment for $10.

Looks like all the transistors are Motorola there, that shape and the dimple on top are very common on parts from them. The drivers are Fairchild.

Not wild about the picture, but the meter works.  I love old Keithley equipment.

I've not had a lot of luck posting pictures, let's see if it works this time.
