Do you have any job skills that are now obsolete?

48. Printed circuit layout using tape and permanent ink on Mylar film.

I also worked from mostly hand-drafted schematics, and had to observe the "rules" about layout for analog circuits (it's much less forgiving than digital, which has at least some noise immunity). I still pretty much do my schematic work by hand, and have only recently started using CAD software to make them. However, I've been using software to do printed circuit work for a long time now, and I wouldn't go back. Actually, I can't--the new SMD parts are so tiny that doing a layout by hand is pretty much impossible.
