TI also sold some wire-wrap sockets (gold-plated to their credit) with 
"forked" type contacts which were welded(?) to the wrap posts.  They had 
the annoying habit of separating the post from the contact fork if 
stressed too much.  Made for some frustrating debugging.

I learned my lesson early on--use Augat sockets.  Your time is worth 
more than the expense.
