A buddy of mine and I bought Kim-1 systems. We did all the usual things, abusing the TTY interface to rs232, overclocking the CPU so it could go faster than 9600 baud, hacking Microsoft basic so it would run on the Kim-1

I wrote an interrupt driven cassette data writer to record data while the foreground was doing something else.

The project was to strap a Kim-1 and a cassette recorder to the chest of a skydiver and record their cardiac data after they jumped out of the plane. We wanted to be able to preserve as much of the data as possible should the skydiver go splat. Kind of dark but you know, programming is not all unicorns and rainbows.

Then I did boring stuff like running fig-forth, building my own floppy disc controller and forth block disk drivers. You know, the usual Kim-1 stuff
