For a while back in the 1960s, Univac was in the 2

like IBM with SLT. They used IC like things, but with all the logic
steering diodes external to the chip.
Interesting, Japanese calcs from that era were somewhat similar: flip-flops,
inverters and some gates in PMOS ICs, but most of the gates composed from
discrete diodes.
Were the Univac "IC like things" recognisable as not being ICs (thick film
modules or such) or were they in some standard IC package?
