I did a little in high school. Part of two of my jobs after college was to GET RID of all the card processing equipment in my facility (first the US Army Ballistic Research Laboratory) and then later Rutgers University's computer center.
There used to be a poster kicking around from the computer museum that showed all the various memory technology: vacuum tubes, mercury delay lines, electrostatic memory, core, and semiconductors. A little research showed that all of them had been used at our labs on computers over the years (admittedly some before my time), we had the ENIAC, ORDVAC, BRLESC, and the Denelcor HEP (all purpose built for BRL). We got the last Cyber 7600 ever built. We also had a couple of Crays, countless PDP-11 and VAXes, some BBN C-70s, and Gould SEL machines before the lab started in on SGI and Sun Workstations (about the end of my tenure there in 1987). This was Reagan-era stuff. In a bad year I bought $2 million dollars in computer equipment each year. The last year I was there, I put my name to the $25 million procurement of the Cray2.
