That's really neat, I missed this on the previous runs I think. One of my very first computers was a KIM-1, I bought it from one of the security guards at a bank where I worked (as mail room sorter and mail runner).

Fond memories. The KIM ('keyboard input monitor') was a quirky little machine, with very little RAM but more general purpose IO than just about every computer today which led to a lot of real-world interface projects. I learned a ton from using it.

Thanks for posting this.
