There was an outfit that marketed a sorta network
using the 5150 cassette
port, for classroom distribution, etc.
There was the Radio Shack Network 2 which worked like that. It was
originally designed for use with TRS-80s (a master disk system used by
the teacher and diskless machines used by the students). I've never
heard of it being used with the 5150 but I suspect it would work.
I did hear of people using the motor control relay on the 5150 (you
could control it easily from Microsoft BASIC, for example) as a
single-bit output to key a CW radio transmitter (morse code), etc. And
I think I read of somebody who used a 5150 as a sales cash register
and used the relay to release the cash drawer.
