Thanks for the memories Wayne! My High School drafting class was just a
couple of years after yours, and I remember it fondly. Everything from
drafting pencils (with lead of various sizes/hardness) to technical ink
pens on vellum.  I enjoyed it so much that I persuaded the instructor to
let me check out one of the old drafting machines for the summer break (I
think it was a Universal).

Just a few years later, in my first real job as an electronics technician,
I was introduced to electronic schematic capture tools, specifically the
Daisy Systems Logician and some Mentor Graphics systems. I spent hundreds
of hours drawing and updating schematics for the EEs at that company. Those
machines were over $100 grand each at the time, with 10MB hard drives.
Then the wirelists went to automatic wirewrap machines, or later, to
specialized board routing/layout machines that were even more expensive.

Now we have free or cheap schematic capture software on PCs thousands of
times more powerful for use as hobbyists.  Amazing. Yes, a lot has changed
in less than 50 years.
