I was recently watching Action Retro on Youtube and saw he had a new IIe case and keyboard he put a GS motherboard in. It got me thinking about if it was possible to build a new Apple IIe. So the case and keyboard can basically be covered with new products being made, as can the power supply and expansion cards, but what about the motherboard? I see there is a new II+ motherboard for sale, but why no IIe motherboard? Is it much more challenging to make? Would it be possible to add enough upgrades to a II+ to essentially make it a IIe? Looking for advise or thoughts.
