The thought of building one seemed ridiculous, but I wondered if a modern design could overcome the issues of size, power and the very real danger of high voltages. The Turner Prize The Valve.Computer integrates eight large printed circuit boards and four auxiliary PCBs, which combine the thermionic valves into a functional general purpose computer. How do thermionic valves work, how do you design a PCB, and how on earth do you get from a NOR gate, to a memory register, via microcodes from a clock and a ROM, to actually run software.
