In my fourth year I had an analog course where we had to hand build
something out of discrete MOS transistors. This "something" had to be a
significant building block on an analog IC, so something like an Op amp
or current mirror alone wouldn't be enough. I built an ADC (four bit,
successive approximation, worked quite well, to save on number of gates
I built my latches out of transmission gates, but I digress...).

Anyways, we were told that we were NOT permitted to use a breadboard, it
must be built using either wire-wrap or soldered together, with
soldering being a STRONG recommendation over wir-ewrap.

Some students choose the wire-wrap method, and they wasted ALOT of time
getting their circuits to work at all.

So, with all that said, MUST you use the wire-wrap technique? There are
MANY reasons soldering is a FAR better idea, especially if you have alot
of connections to make.
