> "if it ain't broke, don't fix it", but [...] Manually entering data in a PDP-11 is a goddamn error prone task. If there is a process involving entering data into a system that's error prone, then it's broken and should be fixed. Thing is, it would also have been broken 30 years ago (the human as the weakest link is not a recent radical discovery made by software engineers - it's one that it took nuclear and aerospace engineers, among others, quite a while to teach to software engineers), so chances are it was fixed 30 years ago. Also, since this is for a robotics system, I think the "UI" consists of servo motors and various sensors etc - not a clunky green on black terminal.
