output production quantities

[grampybear]

Now that I have figured out how to add a new good (Computers) to the goods list, modified Fabio's electronic factory (I just love that building) to also make computers and modified an existing building in game to be computer store, comes the time to actually manufacture them. Is there any guide lines to how much raw material,( steel,plastic,glass ) is required to make a product or what a good output quantity should be?
