I love wire-wrap. not sure if you guys ever saw the IBM1401 and fortran C
compiler resurrected from punch cards by Bob Feretich and company, but it
was 10-bit architecture and all of the memories were wire-wrapped.

Modern (millenial) engineers know what wire-wrap wire is, but they call it

I still do the occasional wire-wrap on small proto boards that I build in
my lab while I'm debugging something particularly if I want the extra
length of the socket for use as a test point. I have to keep trace of my
tools -- the little 'wire wrap tool' that used to cost a buck now runs
about $35 bucks at Frys (due to the scarcity of the darned things). Even
finding the wire is getting more difficult. I had to fix a few cut/jumper
items myself on a few dozen boards recently, and had to go to three
different Fry's in order to get enough blue wire (basically, a bag of 50 at
each store).

Good grief, does anyone do wire wrapping any more? I haven't seen that
since the early 80's.
