Help identifying vintage escrap cards and boards

**FLimits** · 01-23-2014, 08:47 AM

There are some really interesting -- and OLD -- technology components there! I'm in a rush right now and can't ID everything, but I know the things with the U-shaped handles on the top are logic modules from an old computer like a Burroughs 5000 or Univac. They're an example of "cordwood" modular design: "Normal components were soldered in parallel as closely as possible between two or more circuit cards. The benefit of this approach was high component density, an early attempt at miniaturisation. This technology lived on into the early transistor era of the 1960's, and NASA considered it for use in the Apollo Guidance Computer."

Some of the other cards might be from the same system. Did some of these items come from the same source?

I'll try to ID more later today when I have some time. Have a meeting I have to attend now.

Very cool info fl.

The cord wood analogy is neat.

It makes sense.

Electronics have changed so fast huh.

In a few years they say that about our suface mount tech now.... An early attempt at micro sizing.

Def collector value stuff.
Mostly sodier fiber and some gold fingers and resistors.

I would touch and keep for future sale or collecting value. I'm far far from any expert. Solid advice info in posts above.

They all came from the same location, but it was a mix of items there together. I DO however have several boards that say Univac and are in pretty good shape. They are not pictured, but I can add them later if needed. I have a few local buyers interested in some of these items, but I do not trust them completely to offer fair prices. I would like to sell these, and appreciate all help with identifying them as well as any input on value. Feel free to PM as well. THANKS!!
