I had a KIM-1 in the late seventies and for several years I would run into other people who used one, but 1985 seems really late for programming on one of these. For me, the KIM-1 was my first experience with programming and a computer of any sort. It influenced my taste for low-level concepts, not only through x86 assembly programming for graphics in the 90s but much later in the lambda calculus and combinatory logic. I'm tickled that the KIM-1 is seeing such a resurgence of interest.
But that FSK demodulator was incredibly finicky. More than one tape I recall I had to try to read a lot of times while tweaking the playback speed on the recorder!
