From LTwiki-Wiki for LTspice
The first time I ran SPICE, was on a Sperry-Univac mainframe, using punch cards to guide the simulation. Later, teletype terminals allowed a much more intimate connection to the computer and the joy of printing waveforms and spectra on miles of greenbar paper. Sometimes we would flip the paper around to print our character-matrix images on white background.
