Board, connector and wire values for machine control / computer boards from the 60's?

[OhioHomesteader]

Hi all - new new new here.

I have been lurking here for a couple of weeks now. Trying to learn a little.

I am not a buyer - and I am not really a scrapper. Tho my garage is full of it.. LOL

I am helping a friend scrap some NC / CNC (Numerical Control / Computer Numerical Control) machine tool controls at his plant. I need to find out what the circuit boards are worth and the best place / method to get the most money for them.. These boards are from the mid 60's to the mid 70's. The majority of the boards have large gold traces on the component side - a few even have gold traces on the solder side. We also have some connectors in the collection. They all appear to have a large gold plate content compared to computer boards built since the 90's. There are also some connectors (both pin and finger style) in the collection.

I am posting photos of some of the parts and boards.

Any info and help will be appreciated.

TIA

Jim

Hope these images show up..!

Some photos. I have many more and will be tearing down 4 more controls that are different than these. In the future I will probably just post a clickable link instead of consuming bandwidth to image the photos here.

They did not - I will figure it out and add them later.



Well - it is "later". Here goes:

What brand are the controllers? You might get better than scrap on Ebay

Cincinnati Milacron horizontal and vertical machining centers. The old AcraMatic 5 and AcraMatic 100 controls - along with a M&M Precision "operation enhancer" - bypassed the punch tape drive.

High grade telecom Really good money. PM me and we can talk

If you can't find a buyer that needs these pieces something, I would save them in your "above high grade" box until you get a nice supply of them. Then contact a buyer

What you are not still using the tape drive for the programs.
I would search Ebay there still might be a market for the boards.

Sad part is I know where there is a warehouse with a bunch of these just sitting. Typical scrapper problem the owner never gets rid of anything. He thinks he may need these again some day.

Those are beautiful. I know most of the folks here recommend against it, but those fingers and gold traces look so nice I would probably use a heat gun to put the chips out and then run the boards in some AP myself. Who knows what kind of yield 50 year old stuff might give!
