How it started...
My preference for computers originates from the first year in college. Here we had a few hours per week so called computer science. In the classroom there were Commodore C64 and Philips computers. The latest had no screen but a paperrol on wich you saw the output. There was no floppy-drive or tape-unit either but a paper tape that got punched to save the program. The pattern of holes in the tape coded the programsource and could read by the computer for later use.
Soon more...
