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.

Here, you mean where you could actually see the wires wrapped around the
core with the sense, and x, y  wires going thru them.

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.

Know about or use front panel switches?  I never got to use them, but
I know
about them.

While we are in the way back machine, how many know about core memory?

It's front panel switches for me!

OK, how many folk on the list know about front panel switches? ;-)

or 80 column boot straps?

I'll bet not as much as I miss working on the card punches and
readers.

don't forget card sorters for when you drop your deck of 500 cards an
hour
before the assignment is due...
