PCB - Processor Technology SOL Intelligent Terminal Prototype

This is a fairly faithful recreation of the prototype board that was featured in the July 1976 edition of Popular Electronics. This board was never offered for sale to the public; only a set of plans was sold to those interested, along with a letter that warned hobbyists not to build it, as the PCB that eventually became the SOL-20 was already in the works! Keep this board as a memento of a pioneering digital age, or try building it!
