Re: Rotate the monitor
I spent a long time (25 years) in the ROC, and one of the positions I and everybody else had to be familiar with was that of Display A and Display B Plotters. This involved writing information on the back of a transparent screen so that the scientist chappies could read it and work their magic on the front of the screen. Of course, this meant that we had to write everything backwards, and we all became fast and accurate at it.
My day job at one point during those years was as a development engineer in a team that also included a draughtsman. One day he was looking rather glum, he had been asked to write the word OBSOLETE on several hundred old drawings, but in such a way that it could be erased without having to redraw the original content should the part be reinstated. I took a look, all the drawings were on transparent plastic sheets, so I grabbed one and turned it over, and wrote OBSOLETE backwards on the back of the sheet, leaving the front untouched, then turned the sheet right side up again before plonking it on the draughtsman's desk. Cue gasp from Eric, "How did you do that" he inquired. I showed him how to do it, and he spent the rest of the day and part of the next happily writing backwards on the obverse of each drawing.
