No one has mentioned Multiwire.
Can be fabricated from schematics or a net list.
Generally very fast turn-around compared to Printed Circuits.

I have used most prototyping techniques, Wire-Wrap, Multiwire,
PCB, and point to point.

The favorite has gone from wire-wrap to Multiwire.

A comment on wire-wrap robutness.
It's not the wrapped connection reliability that causes
problems.  It't the intergratiy of the insulation.
The insulation can often be nicked as it goes around a post.
It can also were away if the board is flexed or moved alot.

A wire-wrap system carefully built (automatically prefferred)
and NOT MOVED or FLEXED much is a very reliable way to build.
