I use single gates a lot. OR gate= two resistors
and a transistor. AND gate= three R and a tran.
And all sorts of goodies once you add a diode or two!!

Everybody is so lazy these days... I am lucky that
on a daily basis I get to study new circuit diagrams
for cheapie electronics appliances, and yes, the real
big manufacturers still do everything with transistors
and diodes. Apart from LSI of course. Must be that
the good old transistor and diode are still cheaper
and better in huge quantities than cool gizmos
like one gate in a chip!!

Am I the only person here who sticks transistors
between logic chips with hardly a thought?? Or
are people scared by a one-transistor logic
inverter?? Bob?? You with me here?? :o)
