In this 1959 Popular Mechanix report of HECK--RCA's "Home Electronic Center Kid", the following is mentioned: "To speed up the working of electronic computers which assist in such discoveries, the RCA lab recently devised a memory storage plate smaller and thinner than a four-cent postage stamp. It has 256 tiny holes in it and can keep a million facts on file and produce them in any combination or alone in milli-seconds." Does anyone have any additional information about this device? Was it ever commercially deployed? (A couple of interesting asides: Note the "Roomba" in the photo and the description of the about-to-be-produced RCA Nuvistor--and what appears to be a raised floor in the exhibit. And the ghastly "contemporary decor"--could orange shag wall-to-wall carpet be long in coming?) Cheers, Chuck
