Huh I read minicomputer and assumed we were talking about the first home computers, which that was about their epoch. (TBF I don't think any were ever $20 so that's on me).
Although if you go from the Pi 1 in 2012 at $35 at launch, it would be about $50 today.

The minicomputers of the 1960s were only "mini" compared to earlier mainframes; they were still far too large and expensive for home users to even consider. Home computers didn't really come about until the late 1970s.
