Hello everyone. I am seeking information on very high quality breadboard prototyping jumpers that I last saw in the late 1970s in my college electronics lab. These were used with a prototyping board for thru-hole components on 0.1 inch centers with machined female contacts mounted on a PC board, but could also be used with the block type wireless breadboards. The jumpers were gold plated with machined pins (probably around 22 guage) with integral machined female receptacle on the top to allow very easy daisy-chaining. The unified, machined, male/female connector was neatly surrounded by an insulating collar of matt black shrink wrap, from which emerged a wire which terminated in another such assembly. The wire was of small gauge, braided conductor, with high-quality insulation, possibly teflon. These very superior jumpers facilitated rapid and reliable set-up, and the daisy chaining feature spared the breadboard real-estate normally needed to allow multiple connections to a single device pin. Unlike the use of solid wire in block-type breadboards, these jumpers afforded an easy grip, inserted easily due to a rounded pin-end, and would not bend under normal use. I haven't been able to find these in the catalogs. Can anyone provide a reference for this item? Any help is appreciated in advance. Thanks!
