From: "William Donzelli" <aw288 at osfn.org> I have a pair of EAI TR-48 analog computers that I really need to part with. These are circa 1960 machines. From Mr. Cowards site: Operating range: +/- 10 volts DC Computing Elements: Up to 58 DC amplifiers Up to 115 Coefficient setting potentimeters Options: Up to 24 integrators These are large machines, so if you are located far away from Carmel, NY, you would need to call a mover (I could deliver withing a few hundred miles with some arm twisting). One machine has the original operating desk, plus there are a few extra patchpanels, lotsa cords, modules, and other good stuff. Any interest on this list? If so, I should start digging these out of storage. These are for sale, but I would consider trades of old mainframe or minicomputer stuff. William Donzelli aw288 at osfn.org
