I'm trying to identify which General Radio or GenRad test system a pair of smaller items are we recently picked up at auction.
Items are identified as a "2275-4006 training box".
It appears to be a breadboard that plugs into a large tester via a dozen edge board connectors. There are two quick release snaps.
Looks vaguely empty. There is a removable and programmable breadboard on the top.
Age? Value? System? Links?

A photo on abse might be helpful...
Sounds like a card from a portable tester. Any other identifying marks. It may be populated with chips I designed ;-)
