These old cards (with one exception) appear not to have much value. Besides the fact that some seem to be dripping with silver solder, they dont have any components of any value. But the connections have peaked my curiosity. Appears to be a non magnetic silver metal bracket encasing a fiber type material that the is wrapped with the "finger" connection. One card has a tag saying it was repaired in January of 1983. Do these cards have any value. Thank you

Hey, these are a nice throwback to a simpler time (when all I needed was a roll of quarters for the arcade)...
That said, a lot of industrial boards from this era did one specific application (voltage delimiter, relays, etc..) which is nice, but means that not everything is "valuable" from a scrap perspective, as I'm sure you have surmised. Aside from the clock and sequencer boards (probably the exception you mentioned) which might go low telco through Boardsort, the rest are eh.
This is a question for Chris, he might give you a deal given the age of the boards and their potential value, but that is for him to decide. If you want to save some time and effort, if you have a coin or jewelry shop nearby, ask if they have an XRF setup, and then ask if they would be willing to zap some of those traces to verify the silver (probable if they are from '83).
As far as the connectors go, not sure they would qualify the boards for the gold finger rate, considering they are not your typical "gold finger", but again, a question for Chris.

Thank you for ur time and knowledge. In 83 my interests were almost completely on cars and girls. Maybe I should have paid a bit more attention to computers. Thank you again

These range in midgrade to low peripheral
This is the kind of stuff the low peripheral split was mad for. Along with transfer cards you may find in such systems; finger edge connectors on a plain board with gold lines across it.


The small, generally empty, boards are midgrade and you’re better off sending the pins alone. The ones with lots of solder and traces, or wider pins, will make low peripheral.
And ones with heaping solder will make high peripheral.

I’ve sent stuff like this for years.
Fine a memory card or processor card consider ebay, over scrap. They are rarely with much but collectors so love them. And you’ll get at least a few bucks. Look for cards with a dozen little boxes on them.

The clock card is high peripheral
