American Dream Machine
The ADM-3A is an early influential video display terminal, introduced in 1976. It was manufactured by Lear Siegler and has a 12-inch screen displaying 12 or 24 lines of 80 characters. It set a new industry low single unit price of $995. Its "dumb terminal" nickname came from some of the original trade publication advertisements. It quickly became commercially successful because of the rapid increase of computer communications speeds, and because of new minicomputer and microcomputer systems released to the market which required inexpensive operator consoles.
