I did, too.

With home-grown protocols.

With X/Y/ZMODEM.

With a whole lot of serial wiring hand-soldered together, or later with 
pin-insertion, and checked with a breakout box.

With loading code from audio tape cassettes, and I'm not referring to DDS here.

And variously with busted UARTs, or with PIO activity that saturated 
the processor, or other such.

With a side-trip through SCADA and PLCs, too many of the now-older PLCs 
and controllers having completely demented serial protocols.

Times change.

The newer Ethernet pass-through connectors and crimping tools are 
better and faster than non-passthrough crimping, and all vastly faster 
and more reliable than drilling 10BASE5 taps.

We're all slinging a whole lot more data than we did back then, too.

And with vastly better tooling and apps and networking protocols available.
