I think you have a few years on me then. When I was an undergrad, we had a slightly elderly vax 11/780 (iirc) and a line printer that probably deserved 3-phase power.
Oh, this was the mid-80's and the Vaxen were still around, being replaced by stuff from WANG and Tandem .. but that line printer was sacred for some reason, it stayed in operation (after repair) until the late 90's ..
wang went bankrupt in 1992, while the vax line soldiered on for another 10 years or so. anyone that replaced a vax with a wang misread the market badly, particularly with the introduction of pc wordprocessors.
