Subject:?discrete transistor computer
A while ago somebody mentioned thinking about building a
discrete transistor computer. ?I ran across the link again of
the one I saw (only online)

With all SMT, he packs the boards very closely, performance
is of course not so great with discrete junction transistors running
in saturation.

The Rhode Island Computer Museum has four discrete transistor computers.
A PDP-9 and three PDP-8/S systems.
The RCS/RI crew in Providence has a PB-250.
