Reading THERAC-25 material:

>can LF be CR?
>can right arrow be CR?
>can down arrow be CR?
>can fucking BACKSPACE be CR?

What the absolute fuck.

This is software that's supposed to control -- in a safe fashion -- a machine which shoots ionizing radiation and X rays into living people, and they're having a battle over what keys tell the computer that "they pressed RETURN; release the angry ionizing hounds".

It raises the question: can CR be CR? You know, like the operator expects it to be?

@yakkoj that's frightening, but less so if you consider a potential input device could be one of those crazy AS400 terminal keyboards where 'enter' and 'return' are not the same thing at all, and so on.
