For years, I had seen X11 desktops in magazines before Linux and the Intel 80486DX-33 permitted me to first boot X11 on my own machine in 1992 (after installing it from fifty 3.5" floppy disks, which required two trips to the nearest university, as the first time one of the disks was faulty).<p>Still remember that feeling of first typing xeyes & and xlock & and inspecting the result on that 14" color CRT screen (I was beaming more than it, perhaps).<p>Then by winter term 1996 I owned a refurbished HP9000-715/75 running HP-UX 9.03 (also X11-based), pre-owned and via uni discount and still the price of a car at the time... the only undergrad on my corridor who had a workstation in the dorm room (its 21" CRT filling most of the 9 m² space that was not occupied by the bed). My next goal then was to get all the manual books (X11 and HP-UX) - still got 'em.<p>HAPPY 40th BIRTHDAY, X11! And thanks to the X11 authors for making it available for free - imagine, X11 supported mice with 16 buttons already back then!
