Hi @r0the I cloned this lib for the ic7485 on logi7400.circ Noticed it's .md is incomplete as well.

Also do you know, if, with all inputs at "0", shouldn't the output only be "1" at "A=B" / "YEQ"?; instead of having "1" at "YGT" and "YLT"... or am'I having this doubt because I didn't understand the cascading inputs... does "CEQ" need to be always "1" ?
