York had a large Sequent machine on castors. It took eight people to move
it. Nine, actually. Eight to push, and one to collect up broken castors.
Leeds had an Ahmdahl which had all the cabinets on castors. I have some of
the castors (the only souvenir they let me keep), and they're rated for
250kg each. They're rather bigger than the ones on the Sequent :-)
Our present tape backup system, which weighs the best part of a ton, is on
four castors.
Actually, lots of large machines, old and new, are on castors, but they
tend to have jackscrews as well.
