This is a most excellent place for technology news and articles.
My god, if you understand how these systems work, I'm impressed.
I'm good with DC stuff of this era (switches, relays, etc) and man I have to work hard to visualize these things.
I'm seriously impressed with the engineers who designed these crazy complex electro-mechanical systems.
I have some older relatives who were aircraft engineers back when these types of systems were used... Aircraft up through the 70's. I've read some of their manuals... Staggering complexity.
Well, I'd say I understand enough to get by but I did also grow up building RC cars and later working on electronics/computers, so that definitely helped. That said, there's been more than a few times I had to break out a wiring diagram and consult with folks online because I was too scared to break something.
