Ronald (Ron) Nelson, an American electrical engineer, microcomputer chess pioneer, and Engineering Vice President for Excalibur Electronics, since 2010 in retirement. In 1976 he already developed a chess program for an Altair 8800 Microcomputer with an Intel 8080 CPU. Coincidentally, his friend was secretary at Fidelity Electronics owned by Sidney Samole, who just had the idea to build a dedicated chess computer and was looking for a programmer and engineer. Ron got immediately hired by Samole, and they constructed and build several Fidelity Chess Challenger Prototypes, three working models and four non-working models. Sidney Samole decided to promote their brainchild at Chicago's Consumer Electronics Show in January 1977

=Fidelity= Ron Nelson wrote the first programs, and was also Fidelity's Hardware engineer. After the huge success of the Z80 based Fidelity Chess Challenger 7, which sold about 600,000 units, the company along with Ron Nelson moved from Chicago, Illinois to Miami Florida in January 1981. When Dan and Kathe Spracklen were hired by Samole in 1980 to adopt their much stronger Sargon III program as Fidelity's flagship, Nelson focused on hardware aspects and presumely I/O and system programming of the machines. In the 80s from time to time, a Fidelity model appeared with his Z80 program.
