Despite the long silence there is in fact progress this project Image may be NSFW.
Clik here to view. below is the current Fritzing part of this project. It turns out it can't be a single part (at least not if we want schematic to work at all well) as the subparts code gets very slow with 12 large subparts and won't coexist with busses (which this needs). Luckily @steelgoose suggested making the breadboard the base part with static images, then locking it and overlaying and locking the other 12 subsystems as individual parts (making them movable in schematic without being subparts) which seems to work. Please have a poke at this and point out any errors or problems you see (I'm sure there are some still Image may be NSFW.
