Earlier today, I'm watching a youtube of the latest and greatest technology of Western Electric's new telephone electronic switching system, from 1965. If anyone is interested:

An interesting video, the newfangled planar transistors, growing clean but lumpy silicon crystals to a whopping 3" diameter, glass sealed magnetic switches (reed relays)... and then at the end, thin-film deposition of resistors on glass.
Wait a minute, those looks familiar. Really familiar.
The following tiled jpegs, (I finally figured out how to do that, but not very well), the first two are screen grabs from the 1965 video, the last was a photo taken today on my work bench, dated 5-64.
Yup, I got way too much stuff.
