I even once had a wire-wrapping tool, though I do not share Richard's admiration for the technique.

Later, in the late 1980s I started using a pen-plotter to produce positive artwork for acid etching my own PWBs. It was then that I learned OrCad, Tango PCB, and AutoTRAX (Protel). Unable then to plate holes through to a second side, I continued to use wire-wrapping wires to provide continuity through vias and pin-holes (solder tacking it to both sides and trimming it nearly flush). The wire's diameter easily left plenty of room for DIP component leads (flat pins) without even enlarging the hole or pad. And the insulation could easily be pulled off of the wire because of it's very smooth surface and high tensile strength.

The only other technique I can think of off hand, that's definitely gone out of fashion in my book, is the use of dry-transfer strips as etch resist applied directly to the copper.
