OK, this looks very nice and low level. It doesn't deal with 74X packages, just the low level gates. Are there libraries out there for the common packages? To draw out even a 595 by hand would be a pain and I am going to need a bunch of them for this design.
Both their 7400 libraries are missing a lot of the more complex chips. No 193 no 595, and even the 75, though that is no big loss. The counters and shift registers are the heart of the circuit, the other stuff is just combinatorial logic. This is so damn close to exactly what I need.
