I saw the "Hercules" camera, the F4 based Digital camera, also called "ESC". 1MPixel, that was something back then. Long time ago, worked with some of the people that developed it. I worked with Digital Infrared sensors, Midwave and Longwave, in the 1980s. Was not long after that you just bought these, the DCS460c that John Glenn used is in the Udvar Hazy Museum(in a glass case).
