Assembling machine 2's have the same number of module slots as electronic assembling machine 1's (2 slots)
Assembling machine 3's have 4 module slots, like the base game.
Assembling machine 4's have 5 module slots while the electronic assembling machine 2's have only 4 module slots.
Assembling machine 5's also have 5 module slots, which seems a bit weird.
Assembling machine 6's have the same number of module slots as electronic assembling machine 3's (6 slots).
This seems like a really weird inconsistency that makes electronics assembling machine 2's much worse than they need to be. I think this could be resolved by having assembling machine 3's have only 3 module slots and making assembling machine 4's have 4 module slots.
