My dad worked for Univac, in Salt Lake City. For several years, they would hold an open house once a year, and I went to several of them as a kid. This is a real blast from the past for me.

But I didn't realize that ferrite cores were that small. The way they threated them is amazing. I thought it was much more manual than that.

Reel-to-reel tapes! Punch cards! Drum memory! Fortran! Flowcharts! I never used them professionally, but I remember seeing them.

Uniscopes! I did use those professionally, briefly.

What a time trip.
