None, but I do remember loading Autocad from four 5 1/4" floppies. Back when it supported dual displays; monochrome for text entry and some other color display; may have been EGA or some proprietary IBM display. Had to have an 8087 coprocessor, pen plotter, and large digitizer. All seems so boring now.
