I was pissed when I discovered that the cassette tape containing all of my c64 programs was gone. Most of them were crappy, but there was a D&D character generator I wrote when I was 8 that I'd made extensive use of for quickly generating randos for us to play one-offs with.

The oldest publicly released code of mine is SLIPShuttle, which provided pushbutton connecting to the internet on an Amiga (the cmdline interface was terrible). Written in AREXX https://aminet.net/comm/tcp/SLIPShuttle.lha

The second oldest was ringconnectd, which allows you to "ring knock" your (POTS connected) modem to make it connect to the internet and mail you your IP address. It was VERY handy while I was in college, and apparently it took off in Africa a few years later as their internet connectivity grew. https://www.ibiblio.org/pub/Linux/system/network/daemons/rin...

Out of curiosity, what's the use case for ringconnectd? Just to find out what your IP is? What would you need that for back in the day?
