key system diode matrix


I'd like to buy a few of the diode pin blocks and pins used back in the dark
ages for 1A2 ringer matrixing. If I recall, most were 13 pins hight by 5 or
6 pins wide.
Any ideas as to who may carry key system stuff?
Thanks in advance!

I only had the 6x6 diode matrix blocks (6 lines by 6 extensions), with expansion pins for building larger matrices. Haven't seen these in over 12 years.

You wouldn't possibly be interested in a Gen-You-Wine 3-volume set of original manuals for Bell/WECO 1A2 would you? Complete/fair condx. Binding is broken on 1 of the books but no pages missing.

The Smithsonian, I bet... Failing that, hamfests.
But that diode block was nothing magic; you should be able to build your own...

If someone will LEND them to me, I'll scan them and return PDF files, along with the paper.

I could build my own, but this is for a project for our office building that has 30 or so heat pumps with individual timers throughout. I want to reduce the 30 timers to just 7 plus 1 for the cooling tower... 7 channels offering various day/week schdules for the varous offices.
The simple to insert diode pins would let even the parking attendant to change offices by changing the pins.
Yeah I know, there are probably many $50,000 HVAC controls that will do this, but come on, a Grasslin Talento 8 channel timer, a bunch of ringer matrix blocks, and a bunch of relays to replace the individual timers costs less than a grand.
So.... anyone remember Telectric on Venice Blvd in Los Angeles? I used to shop there... the old guy, who kept a bottle in his desk draw (and who among us doesnt?) used to bore us with stories of selling cable to the USNavy to be laid on the ocean floor :)
Someone has to know someone who sells old 1A2 stuff....

Try Source, Inc, in Dallas. They used to carry it all. Used warehouse full of stuff.

I had a couple of those laying around. Actually, some closets in some bldgs still have the whole key system on the backboard, even tho it's been turned off for more than a decade. I also have some PSes for the key systems.
Email me at snipped-for-privacy@hotmail.com and include NOSPAM in the subject line, or I won't get it.

There was a good special on the first Transatlantic telegraph cable on PBS recently. Good ol' Cyrus and the stuff about Lord kelvin's mirror galvanometer.

I know that some old 1A2 stuff comes up for auction on Ebay.
