Mathematics or? ? ?= When I started in 1969, displays certainly were not commonplace, but we got the jobs done anyhow. All our (administrative) jobs started as punched cards (later data-entry on IBM 3740), were read via an IBM 2540 card reader / puncher, handled on an IBM 360/40, with output on e.g. the venerable 1403 printer. Data was kept on magnetic tapes and 2311 harddisks, with each a whopping 7.25 MB capacity. So, when you had to look at something, you looked at fanfold paper, with holes on both sides. Other applications could put holes in cards /Nico -- I am using the free version of SPAMfighter. SPAMfighter has removed 1222 of my spam emails to date.
