First computer experiences were with a Commodore CBM 4032 (and state of the art 5¼-inch dual floppy disk drive) owned by one of the physics teachers at school.
Sitting down, unsupervised, with a group of friends one lunchtime we quickly tired of typing in rude words only to see “Syntax error” every time and we all wanted to find out how to make it work for us.
Lost touch with one of the group, but the rest of us all ended up in tech or software development of some sort.
Old enough to have used, installed, and maintained V21. And most of the CCITT/ITU data transmission schemes which followed. Also a well known 50 baud network that went before 🙂

It was modified by my uncle to work on the commodore aniga (basically a switch on the back to just force modem on/off, so you dialled the number on the phone flipped the switch and hung up phone).
