Another story of using old technology: a couple of years ago I wrote an article about the
invention of FM radio, in Holland in 1919 (no, not by Armstrong in the USA in the late
1920s). I wanted to simulate the circuit used, and found the easy way to do that was with
complex number arithmetic.
So I wrote a simulation of the circuit in question in ALGOL 60, running in a SIMH
emulator. In other words, simulating a 100 year old invention using 50 year old computer
technology. Why do it that way? Why not?
Fun.

I like how having the old hardware gives physical
"witness" and "evidence"
that all the old stories are true - people did invent and create these
things, they didn't just appear from aliens.
Indeed. I am teaching a security class on TCP/IP and I recently got my AT&T 7300 PC
up and running with its Ethernet card and Wollogong TCP stack.
