Glad someone finally got around to this point Myke. I too am a fan of
wire wrap and have used it for small and large prototypes, however
having all your PIC circuitry on a 30 pin SimmStick module means you
only have to wire wrap, or solder point to point your specific I/O.

And when you have finished your birdsnest, and finally have it
de-bugged, you then pull out your SimmStick and re-use it in your next
project.

New SimmSticks are now appearing that may even cover your specific I/O
task.

Interfacing to the SimmStick can be done via a set of 30 male/female
pins, or a 30 pin memory module socket. This lends itself readily to
breadboard, and veroboard interfacing.

SimmStick also has proto type boards, so for a one off design, the
SimmStick proto board becomes the final product. You only need to join
your CPU board to your Proto board with a simple bus using veroboard or
male/female pins. Suitable veroboard that has 30 tracks in parallel at
.1" centers must be one of the most common boards available off the
shelf.
