When searching for information on the state of this software (to answer the dreaded "is it dead?" question) I found some information here (and wanted to share): https://steamcommunity.com/profiles/76561199415539956/posthistory/

Would you be interested in adding relays like the ones vehicles use im a mechanic and really want to create a computer i designed using relays

I've been building a circuit with a 4bit adder and was getting some strange results that I couldn't explain. It appears that 1 + 3 = 8. See picture below. Is that right or am I reading something wrong? S3 is high and represents the four bit which represents 8 correct? This happens two more times for addition where A0 and A1 are both high. 1 + 7 = 12 and 1 + 11 = 4. Please explain what I might be doing wrong or maybe a bug. Thanks for helping out!
