Found out from my local yarn store that a regional yarn store had new-in-box electronic #knitting machines on sale incredibly cheap. Unfortunately (fortunately?) they had sold out by the time I called them. Not that I had the space for one, but it seemed too good to pass up.

This sort of tech seems to have hit its heyday in the `90s from the bit of research I've gathered so far.
Adafruit had a project to "modernize" the interface to one:
@kyle Oh, that's very cool. That looks like a lot of fun to work with.
