Paul's Old Crap is a video series filmed by Paul Lezica and showcases some of the old computing hardware in the Higher Intellect Technology Museum. See below for links to individual episodes of the show.


Over the years we've both collected and lost a number of items in our tech museum, so the decision was made to showcase what we've got as a retro video series. Our aim is to display some average use of each system along with discussing technical details and how to keep these systems running.


Due to space availability we might not be able to accommodate large system donations, but we would welcome donations of components which could be used to upgrade systems in our collections. If you're interested in helping out, drop us a line at admin(at)
