An assembled RC2014 Zed Pro modular Z80 hobby computer, which comprises a backplane about the size of a paperback book with playing-card sized component circuit boards plugged into it vertically. This particular Zed Pro is the limited-edition Pride kit, where the component boards are coloured so that they form a rainbow when arranged in the backplane. The computer rests in the hands that assembled it, which here are sporting some fairly long, blue-varnished fingernails. All of the electrical components, including dozens of resistors, headers, and IC sockets, were placed and soldered with the fingers and fingernails shown.
