That is awesome. I love relays and do some relay logic reconstructions. But nothing of this volume and complexity. Do you have a documentation for this project?
Yes, you find a lot of information in www.relaiscomputer.at, for example a link to the project-log, some design information and a 95% valid circuit diagram.
I’m not very familiar with relays. How is addition done with them? Do you use Half Adders, and how are they constructed? I assume the ‘AND’ function is achieved by adding voltage, but how is the ‘XOR’ function implemented?
Hello, for the addition I use half adders in the same way than classic logic using and/or/not. The "and" function is realized using a relay (one input is realized by the coil, the second input is one of the input pins of the relay switch), the "or" function is realized by diodes (yes, you can realize the or using relays, but diodes are cheaper and easier. Not perfect, I know, but here I made a compromise). And "xor" is a little circuit using two relays. You can download the complete circuit diagram of the system from the homepage.

im gonna use my handheld computer to do 1 trillion calculations to display this video about 1 calculation
