Externally, the only benefit of the older machine, other than the paint, is the keyboard. Better feel than the newer versions. Louder, yes, but, feels so much better. Electronically, the computers are pretty much identical. Enhanced ROMs can be moved to the earlier board (provided it's a Revision B board, Revision A boards can't do Hi-Res graphics correctly for some reason), giving the machine full Enhanced //e status. Mine is that way. Swapped the chips over from an '85 Enhanced unit, and peeled off the "Enhanced" sticker around the power light, then slapped it on the 1983 machine.
