#telephoneexchanges — Public Fediverse posts

Now this is a nice find!

I've been passed a scan of a notebook from the late 1950s containing details of all the #telephoneExchanges in the UK

This sort of information was used by #telephone enthusiasts (UK #phreaks) to navigate their way around the toll (trunk) network

There were various techniques to get yourself onto a trunk, but once you were there the dialling codes in this notebook would get you anywhere in the country!

I love the art style on this poster produced by Post Office Telecomunications in the UK.

These posters would have been at least A2 in size, and were available to schools to help teach students how to use the telephone.

I'm not sure of the date, but I would guess late 60s - early 70s.

You may not like it, but this is what peak performance looks like. #WutheringBytes #TelephoneExchanges ☎️ :blobfoxhyper2:

I bought an analogue panel meter recently that reads up to 60V DC full scale deflection. These are super handy for monitoring the supply rails in my #strowger #telephoneExchanges

What I love about this one is the tiny wee screw base lamps it uses for the scale illumination!

So smol!
