Regarding paper tape, I used to work for National Air Traffic Services, who used paper tape for loading maps and coastlines for the radar screen at the main air traffic control centre. The system was used old mediator processor dating back to the mid 60's, and was used up 'til around 1995/96. Incidentally, the mediator system also controlled the RAF's touch screen system (a CRT with copper wires protruding from the front). Again this was in active use until 1992, when a new state-of-the-art system replaced it Ooh the good ol' days ;-) -- --------------------------------------- Stuart Bailey BSc (hons) CEng CITP MBCS LinuSoft (Proprietor) Linux Specialist (01953) 601294 (07778) 383739 http://www.linusoft.co.uk ---------------------------------------- ********************************************************************** This email and any files transmitted with it are confidential.
