“Jungle” Is a Breadboard
THE electronic jungle in the foreground is the breadboard, or first working model, of the new miniature four-binary module held by a Bulova Research and Development Labs engineer at Woodside, N.Y. All the elements of resistance and capacitance to the prototype jungle are contained in the tiny device to be used as a timer in space vehicle controls.
The small module was known as a cordwood module, where the components were stacked together not unlike a cord of wood. Interconnections were done at each end. Monolithic and hybrid IC’s made this electronic assembly technique obsolete.
Hey, KH; thanks for posting that blurb. At first I thought you were BSing, but I reread your post and realized – no, I’ve seen modules like that, and that seems an apt description. A quick lookup, and a little surfing later, I found out about an interesting technology called “multiwire” boards…
Yep, that’s it. The smaller the device, the better for use in aerospace.
