I saw these on eBay, and figured the PCB was attached by the calculator 
manufacturer. I'll have to get one.

When I think about using conductive epoxy, I worry about shorts between 
conductors. How do you avoid that? 

Any chance you'd put some of the boards up for sale? No idea where I'd get 
.020" thick boards made in small quantities...

Yeah, I had a small collection of Panaplex displays from Radio Shack 
display assortments that I threw in the trash, thinking there was no way 
for me to ever use them... And to think of some of the junk that did get 
saved!

I have a pile (~1K) 11 digit calculator displays and eventually settled on a 
0.5mm thick double sided translator board installed with conductive epoxy.  The 
connection now becomes a simple DIP header: http://www.ebay.com/itm/140729423185

I remember having a bag of the clips back in the '80s and thinking... "When

I have one of the four digit versions as well as one of the six digit. They 
are screaming to be made into clocks!

Does anyone know of a source for the connectors for these, or ideas on how 
to make one? I've scoured the 'net and came up empty. 

So far, the best idea I have is to cut some phosphor bronze strips, fold 
over the ends to make a sort of spring, and solder them onto a .100" header.

I've built a large number of Panaplex-based clocks over the years, so am 
well used to them. Just checked - still got several 100 displays, including 
a lot of SP101s and for some reason, trays of SP336s as well a a few 
"exotics".

These CM (Custom Module) displays have already been probed - the hh:mm:ss 
variant has duplicate segment pins for the left-most digit - both displays 
were reluctant to light fully at first (as are a lot of Panaplex displays 
which have been in storage for a long time), but a bit of persuading and 
they're there now.

Since it's multiplexed, there should be 4 or 5 anodes (and obviously 7 
segments) depending upon how the colon, AM, and PM connections are made. I 
counted 18 pins total, so it's very possible there are individual cathodes 
for A,M,P,M, and each of the 2 dots in the colon. This is what was done in 
the SP-151 display I have in my wristwatch.

BTW, the SP-151 is probably an earlier-generation display because it has 
visible contacts that appear to touch a thin film deposited on the inner 
surface of the frontal glass. I'm sure the pinout is similar to your 
Panaplex.

As far as identifying the anodes, you will eventually find them by 
trial-and-error. Just be careful to limit the current to very low values, 
maybe 100-200uA. Remember there's no need to apply full-rated current (ie, 
full brightness); all you need is just enough current to see a faint glow 
to ID the pins. You will inevitably apply ~180V across 2 adjacent segments 
(which have almost no spacing), so a very high electric field will be 
present which could damage the device if done for extended time. You'll 
probably see a blue dot.

Just noticed that these don't seem to have an obvious anode connection - 
has anyone powered one up, and if so, what sort of connection did you use?

You can see the anode (transparent-ish metal film over the face of each 
digit), but no obvious way of making a connection to it, though the metal 
film does seem to extend into the connection area for the cathodes. I've 
tried taking a photo of it, but being transparent, it doesn't show up very 
well !

Ah I see. That has me wondering what a nixie tube made completely out of 
uranium glass would look like.

Try this...
https://en.wikipedia.org/wiki/Krypton-85

You might be surprised at the number of tubes that over the years have had 
'radioactive' contents. Many gas discharge devices had it added to regularise 
the characteristics for light/dark operation (trigger tubes and regulators) or 
their trigger parameters (eg TR cells). 

Some of the WWII era radar devices [and later ones with warnings displayed] 
have truly dangerous types and quantities of 'radiation'. There are web lists 
of tube types.

  What does the Kr85 stand for? I see it on one of my displays too.

Nice!

There is also a 6 digit version of this, but has no white backside.  Saw it 
on ebay a few days ago.
