I've just checked my archives, and I have a copy of the original two-part artical, called: Build the Micro D-Cam Solid-State Video Camera Part1: The IS32 Optic RAM and the Micro D-Cam Hardware - Sep 1983 BYTE Part2: Computer interface and Control software - Oct 1983 BYTE I also have a copy of the Micron Technology IS32 OpticRAM data sheet. If anyone is interested, I can scan them and post them for public consumption.
