In case anyone wants a brief intro to Multiplexing

[–] [email protected] 10 points 1 month ago (1 children)

Ah the era before duplex/multiplexing (is that the right term?)

Can't stop the signal, Mal.

Makes me wonder if Valve saw that and got some inspiration for Half Life...

I had the same thought! Immediately pictured the very beginning of HL:Alyx

That thing is gorgeous I want to see something like that with my own eyes now

[–] [email protected] 11 points 1 month ago

Genuine thanks OP, I had no idea it was ever like this

Hey Mr Technician, there's a wire disconnected

Where? Which one?

I don't know :(

[–] [email protected] 21 points 1 month ago (1 children)

I assume they knew precisely which cable was where and all that. I bet it was all labelled with handwritten notes (probably cursive) and they must've had a ledger book etc. Pretty fascinating stuff to think about tbh.

lol .... imagine reporting into work one day and realizing the ledger or handwritten notes have been lost, burned, destroyed or missing

Now I understand where Simon Stålenhag gets the inspiration.

Before fiber/digital (able to carry multiple call streams on the same physical conduit), when all phones were analog on copper, this is how all telephones were wired, just with smaller wires all bundled together, and often buried underground.

[–] [email protected] 9 points 1 month ago

Not quite. They figured out how to get more signals on one cable full before the digital era

[–] [email protected] 13 points 1 month ago

Uhm, no. Multiplexing also existed in pure analog times.

That makes early fears of power and telephone cables eating the city and everyone in it more understandable.
