10-tall production cell of processing units.
Inputs:
- 1 full belt of green circuits
- Either a full belt of reds if you are lazy, or a 50/50 red+green belt
- 1 pipe of Sulfuric Acid
Outputs:
- Blue circuits
I use 3 of these designs stacked to feed 1 blue belt of processing units for my main bus, but I think 2 of them is enough to saturate it. I haven't done the calculations, because I don't really care about such things.
It certainly can eat a full belt of greens if you let it.
