I've been using COVID as an opportunity to deep-clean the couple of used Unicomp buckling-spring keyboards I snagged at a good price as spares (since they don't make standard US104 layout anymore) and I noticed that one of them not only had the separate keycaps and keystems, but that it had a whole bunch of different colors of keystems, so I decided to have some fun putting them back in.

(Yeah, the keys that are always one-piece designs are yellowed. I'll order some replacements eventually.)
