Well, I started out on an IBM 1620. Still have the programming book around the office somewhere (it's fun to pull out for visiting students). BTW - my recollection of the 1620 is that it had magnetic core memory, and was the first commercial solid state computer. Moved on to the PDP-8 and PDP-11, complete with front panel switches. There was a tech in the lab where I worked who thought he could fix any programming error by randomly changing memory contents... Success usually eluded him. Speaking of switches, when I came to Evergreen in 1985 they were still running an HP-1000/2000, with lots of lights and switches :-) And a paper tape boot/diagnostic loader. I still have a 16KB core memory stack from it. Anyone remember when an 8KB core memory board for a PDP-8 was nearly $10,000? For me, that really puts things in perspective.

Connecting to different systems meant throwing big two or three position switches to change which system talked to other systems. Plugging in the bootstrap program either push buttoned lighted indicators or toggle switches on the front of the data general nova or eclipse computers.
