Help with clock identification..

[Kerry Borgne]

Hi Guys,

 Was here under my old ID of Orange_Glow_Fan but somehow (old age!) forgot my ID/Password and the email address it was associated with so here I am under a new ID...

 I picked up this old clock and wondered if anyone had an idea what it is.. Looks hand made, I think,  at least hand wired. Pretty nice work.  The display is made up of incandescent bulbs
(CM344, 10 volt, 14ma) All ics, no micro.

  I also need help figuring out how to fix the segment 'mask' as you can see it's pretty well toasted!

 The clock seems to work as far as I can tell, but there only a few bulbs still working so I can't be positive it's fully functional. Finding the bulbs is going to be a real challenge. At least at a price I can justify spending..!

Chicago Miniature (vcclite.com) still makes the #344 bulb. Onlinecomponents.com has 'em for 41 cents apiece (less in quantity).

I have a sack of 500 similar bulbs, but they're 14V.

Definetly home brewed. Great point to point wiring. The voltage regulator is 6944 = 44th week 1969. So early TTL stuff.   I built one myself but found that AC voltage transients (vacuum cleaner was especially bad !) kept disrupting the correct time. Taylordan has a similar design of TTL logic with nixie readouts.

Hope you get it up again. I'm always on the lookout for these early home-mades and have quite a few.
