The XOR patent was https://www.google.com/patents/US4197590
Has a priority date of January, 1976, so the Cromeco Dazzler (1976) was 
released (probably) after the patent's priority date documents were 
filed. Hence using it as prior art in the commodore case would not have 
helped, unless there is notarized documentation showing it was working 
in late 1975...
