Xerox 530, Sigma 3 and Peripherals

From my analog archives, a Xerox 530 computer is in the foreground, the Sigma 3 is in the background. Thanks for having a look. The 530 uses solid state memory along with other more "modern" components than the Sigma 3. They used the same instruction set and operating systems, thus we used the 530 for software development. This was taken in Skokie, Illinois at a life sciences R&D facility.
