First thing I wanted to know was whether or not it had made use of the 4 bit slice ALU (which imho would have been ok) but unsurprisingly this is one of “those” projects..

But yeah the alto became my new favorite even though it’s way before my time when I saw the cpu card for it, and I really see no reason to take exception to the 74181 other than it’s too complex— the whole ti 74xx series is complex in retrospective. Unless this is somebody with the means to substantiate lithography for many of the TI chips but not the 4bit slice alu, then I’m not really sure what their hang up is with it.
