Has anyone come across any resources for instruction sets optimised for hand input? I assume there are as many pre RISC instruction sets optimised from programming in assembly directly rather than as a compiler target.
- Gibbon1 4y agoGuy I worked with said he used a mainframe that you had to clock in four 32bit words and then hit run and it would boot. And a newer one where you had to enter one 32 bit word. I think the instruction was like read X byes from the input device port into memory starting at address 1.
- t344344 4y agoYes: - programmable calculators in 1970, HP something - 'human computer', set of instructions how to calculate stuff by hand. Turing had chess engine, there was 'paper computer' in soviet tech hobby newspapers. - mathematic equations
- benj111 4y agoNo I mean with toggle switches. So it might be optimized for the binary codes to be easy to remember or have as few 1s for common operations.
- tyingq 4y agoI don't know that it was done to optimize for hand input, but see the instruction list for the PDP-8: https://gunkies.org/wiki/PDP-8_architecture https://gunkies.org/wiki/PDP-8_architecture
