Relay Computer 2020 Review: Demonstration

As I've now reached a significant milestone where my relay computer can perform branching it's time for a short series of review videos to cover off what's been achieved so far and to look at what's coming next. In this final episode I put everything shown so far together and load the Fibonacci program in to my relay computer and give it a whirl.

These are the episodes in this 2020 update series:

The architecture of my computer is based upon the RC-3 relay computer at the Museum of Computer Culture by Phil Ryals and his team which is itself based on the Dr Harry Porter’s relay computer (HRPC). The following sites are also worth a good look and have a wealth of information available:
