I was originally dismissive of the Dartmouth ‘time sharing’ system.
One could not interact with his running program.
A few years later I studied it more closely and became highly impressed.
Kemeny had produced a highly useful system with minuscule hardware.
The turn-around time was quite small and that is immensely important.
The editor ran on its own small machine and was simultaneously aware of all the terminals.
A user interactively edited his source program at a terminal and interactively examined the output.
Another slightly larger machine ran queued “batch jobs” with a short time limit.

<p>I now consider that system a jewel of originality.
I still don’t know whether to call it timesharing.
