Thanks for all the replies, Multiwire was indeed the name I had forgotten.
Rather easy to forget... it's not a very unique name, there being lots of things
that could fittingly take on that name.
I didn't remember the eyelets at the IC pins, but as Dwight mentions them I
have a vague recollection of examining a board and (without knowing better or worse)
raising an eyebrow as to the potential for manufacturing (in)consistency and
the possibility of either cutting the wire too deeply, or not enough to
maintain a good contact.
Interesting that there was such a wide range of experience with it's
reliability. I wonder if it was board size, or variation in quality control
between manufacturers of the boards.
