Keywords: coco 6809 Message-ID: <8481@c3pe.C3.COM> Date: 19 Mar 90 02:08:34 GMT Sender: charles@c3pe.C3.COM Reply-To: charles@c3pe.c3.com (charles Green) Distribution: usa Organization: C3 Incorporated, Herndon, VA Lines: 11 The local Radio Shack says they have no books on the 6809 CPU, and I can't find one at the local bookstores either. Can anyone point me to a source, or title/author/ISBN#? I'm just curious about the instruction set and how it compares to the 6502 in my Atari 8-bit (*anything* has to be better!) and to the 8080/Z80. It *must* be better; those other chips don't have OS/9! (do they??) Please reply and I'll summarize. Thanks, Charles Green charles@c3.com
