We had these in our high school computer classes my junior or senior year and we joked about doing it (learned from either Compute! or Byte magazine or some bbs thing) and our teacher also knew about it and immediately sternly warned us not to do it. Computers were so expensive and difficult to access at that time (depending upon your age/income/location) one would have to be pretty irresponsible to do it. For reference one of my classmate's father worked at IBM and they had a rare IBM PC at home with a diskette drive, and our only other computer usage reference was the mini computers we got access to at our community college that via something like a VT(some number) with green or orange text terminals for DEC and access to some other mainframe that printed out reams of paper when we played Zork on it.
