Apple II vs Apple II+

[Ronald Wayne]

>From the Apple ][ Reference Manual:

"The Apple II Plus is a standard Apple II computer with a Revision 1
board, an Autostart Monitor ROM, and the Applesoft II BASIC languae in
ROM in lieu of Apple Integer BASIC.  European models of the Apple II
Plus are equipped with a 110/220 volt power supply."

It goes on to discuss the differences in the ROM.  Revision 0 and
Revision 1 mainboards are discussed elsewhere.  I believe that Apple
had several mainboard revisions after this was published, and that
Apple was using Revision 1 boards for the Apple ][ as well.
