If you mean terminals that push onto a .025" square post, they were
from Dupont Berg. Crimped as jumpers and covered with heatshrink by
Augut or Cambion or one of those wirewrap breadboard manufacturers.
(Damn expensive that way). Damn expensive in any way, originally.
The Berg hand crimper was a better part of a kilobuck. Something like
$650, just for a hand tool. "Crimp to Wire MINI-PV" seems to be the name
of the line. "Mini-Latch" for the housings. Both single row and double
row on .1" centers. (I don't know if they make this stuff anymore.
Newark and Allied both had it).
Jameco sells the stuff or a clone of it, under the catalog section '.100"
Non-Polarized Connector Housings and Crimp Pins'. Item number 100765
for the terminals. The open barrel crimp part isn't that unique so an
inexpensive crimp tool that will do subminiature D terminals or Molex
KK will probably work. (Molex KK connectors use a single spiral leaf
terminal and need the side of the connector shell to force contact.
The Berg type can be freestanding).
Another option are connectors designed to go on single row .1" headers
that have insulation displacement connections on the other side where
you force a wire down into a slot and it gets connected. A nylon shell
with terminals on .1" (or .156") centers. Panduit "Mas-Con" is the stuff
I've found surplus, but Methode "Jaguar" was another one, and Molex had
some stuff like this, too.
