Even before that. The System/360 machines were typically leased, not sold. And the leases had different tiers for different clock speeds. If you decided you needed more power, you'd call up IBM, accept a more expensive contract, their service rep would show up, unlock a padlock on the machine, open a panel, turn a knob, close and lock the machine again, and leave. |
