Eico test equipment and IC finds

I was recently tasked with cleaning the house of a retired EE-hoarder. I'm still cataloging the mountain of IC's he had stashed, and the list will be posted here once I have it finished. Among the more interesting finds, an AMD Data Ciphering chip sample (1984, hardware DES) containing three different versions of the IC. The bigger problem I have is an Eico Model 470 (not 460) oscilloscope he had. It's been touched, and a part is missing. I may be able to repair it, if I can lay my hands on a schematic or original manual. I've found two on the web, purporting to be correct ($4 for deadtree, snailmail; $20 for digital). Does anyone have any info on this oscope? I haven't found it in an Eico catalog, Sams Photofact, the BAMA archive, or anywhere else.
