Completely random aside:
Noritsu manuals were just the best. You could rebuild a System 2 from the circuit diagrams.
Fuji: “A fuse is blown. Replace it.”
I’m not exactly sure why I thought of this old memory … but since we’re being old guys….
I remember when schematics were glued inside radio and TV sets. Youngsters don't even know there was a "tube era". They also don't know about the hundreds of very lovable mini-computers. CRTs for picture display is something they've never seen. Typewriters were lovely contraptions, especially the IBM Selectric.
I'm glad we are old farts together.
