The introduction of the PDP-8 series was a disruptive, game-changing event, in that it made computers available to a large group of scientists, engineers, and tinkerers. For the first time, more or less, you could walk into a room, sit down at a teletype, and start programming. No more “batch jobs” and “reserving” time on a huge, scarce, over-booked, expensive machine.
Instructions and memory The PDP-8’s instruction set is very well documented elsewhere.
