Lots of transistors, aren't there? I think of the
PB-250--a
minicomputer (even though the name didn't exist then) with about 300
transistors and a mess of diodes. 21 bit words+sign,
magnetostrictive recirculating memory. Powered from a standard wall
outlet. Bitsavers has very complete details, including circuit card
schematics.
The SMALL and the BIG. Looking at the ICT 1301 around here.

Last years open house video was what caught my eye.
