Re: Question about Apple ][ ROM chips!



I just found http://www.classiccmp.org/mail-archive/classiccmp/1997-06/2930.html
and read about something called an "RFI motherboard" that seems to be
similar to what's in the 1979-copyrighted board.  The post also says:

"According to my docs, Apple II's were made with all three
motherboards.
Apple ][+'s have Rev 1 or RFI motherboards."

The fact that one of my boards is apparently a Revision 1 doesn't help
me narrow it down any, I guess, unless the "MEMORY SELECT"s were taken
off Rev 1 for the ][+.

Oh yeah, I forgot to add: on both machines, pressing "Reset" alone
seems to work; Ctrl-Reset isn't necessary.  Is this function unique to
the motherboard, or is it part of the keyboard's board (and therefore
keeps the motherboard's authenticity in question)?
