Cool thread! I thought of something I could contribute, an ed session captured just now, which as I came up with it, reminded me how not bad ed is: $ ed hello.c hello.c: No such file or directory a #include <stdio.h> int main() { printf("hello, world!\n"); return 0; } . w 75 q $ cc -o hello hello.c $ ./hello hello, world! $ okay, so that could ...

It's perhaps worth noting that line editors were originally developed for printing teletypes, before addressable CRT terminals were widely available. They did require a certain amount of holding your program file in memory, although you could print out sections of the code. In practice, this was a cognitive skill that programmers using them tended to learn....

I haven't used 'ed' seriously, but I've used several line-oriented editors: the Eldon 2 'amender' (EE KDF9), the George3 editor (ICL 1900), SOS (TOPS-10, on DECsystem-10). They all are similar editors, though with one significant difference: could you revisit 'previous' lines in the file or not? The George3 editor/Eldon 2 amender were, if memory serves, ...

Using either styles for all Unix operating systems in general is correct, but you can not claim that a specific version of Unix is named UNIX unless the current or past trademark holders (currently ...

As other answers will point out, you simply need to ensure that you have a teletypewriter that can talk ASCII and a way to make it communicate over a modern serial link such as RS-232 (possibly via an adapter as used in the video), and the rest is exactly the same as you'd do if you were using a terminal program on your Mac. (And probably a USB serial ...

The presumption in this situation is that there is some computer out there that already has one or several modems connected to phone lines, set up to automatically answer incoming calls and establish terminal sessions on them. I'm not going to go into detail on how this is done. Once that's in place, connecting using an Model 33 ASR is similar to ...
