Quadri Core memory?

I recently found what looked like a solid block of aluminium recently but on closer inspection it turned out to be a 64k x 18 core memory made by Quadri Corporation. It's part number is 1-0805-0015-02. It measures 1 1/2" x 6' x 9" and all the case parts are machined out of solid aluminium and it fits together so well that the joints are barely visible. It's very obviously military. It looks like it could survive WW III! I did some searching for Quadri and found that they used to be a manufacturer of high reliability core memory systems used in military aircraft, helicopters, tanks and other vehicles but they have been bought out by a company by the name of Agro-Tech and no longer exist. Does anyone know anything about the Quadri core memories or know anything about Quadri? Joe
