I like the singular inverter schematics, because I find the more helpfull,
not only in figuring out how it works, but also desighning bots. I dont
think that when newbies see a pictoral "chip" type diagram they realizse
that they can use any inverters on the chip, not just the ones the the
person who drew the diagram did. I could see a newbie with a great new type
of bot or something, needing to use some extra inverters for a sub system
(vision, reverse, PNC, etc.) going out of thier way to use the last two
inverters on the chip because the microcore diagram uses the top four.
although they could easily have just used the last four for the microcore
and have the free inverters at the top where they need them. Do you
understand what I am getting at (too many run on sentances?). this would be
escpecially anoying if they try to make a PCB, having tracks running from
the back of the chip to the front because thats where they need them.
also the singular inverter schematics lead to more creativity among
newbies. pretty much every bicore I have seen looks exactly like Ians
schematics, even if it is less convienient.

thats just my thoughts.
