We are talking about the 3M prototyping system where wires are pressed into
narrow grooves in the pins on the back of the board, right?

My experience with this was much the same as Rusty's.  I had to build a ROM
emulator sort of thing to use as a tool, not a prototype.  Being a software
guy, and having had bad luck with wire-wrap before, I thought this 3M stuff
would be great.  Through the assembly and debugging stage, it was much more
convenient than wire wrap.  After a week or two, things started getting
flakey.  I thought about soldering all the wires in place after the thing
was debugged, but the sockets and other plastic parts seemed to melt easily.

Next time I'll do it right.  I'll get a hardware tech to do it for me.
