Don't forget that 16L8 means 8 logic outputs and 16 inputs even though
at first glance there only seems to be 8 inputs. That is because every
output is also an input and can possibly be just an input by forcing the
three state option.
One of the L8s uses an output as an input, but the design does
not use
any tristates or feedback on the L8s, so my job is easier. The R4 and
R6 are harder, though, as feedback is used on one, and both have registers.
