Our 3031 had a whole room full of IBM 3033 removable disk drives... Each
'disk pack' must have weighed a good 20 pounds too!
Capacities of from 200 million to 1.6 billion bytes in increments of 200
million bytes.

Ahhhhhh, those were the days! You had to be a weight lifter to work all
night long changing disk drives!
I carry more storage than was available in a whole 3330 unit, on my
keychain today!

Nowadays, if you want to see literal core memory for yourself, you need
a museum. (As I recall, Boston's Museum of Science has some.)
Hard enough trying to scrounge up a picture of an old-style removable
disk pack (that's what I use for drive icons on my Mac).
