In early to mid 70's, I remember buying bags of surplus transistors from
Poly Paks real cheap. Then we wired them into discrete logic gates and
flip-flops to get some rudimentary type of computing device. It was an
arduous process but a challenging one. But then we saw that TTL chips
were getting cheaper at Poly Paks so that fad quickly faded.
