Subj : Why $0401, $0801, $1c01? Why not $0400, $0800, $1c00? To : All From : pzembrod@gmail.com Date : Fri Feb 12 2021 07:27 am Hi all, I figure that someone here probably knows why CBM's basic RAM always started at $xx01 addresses, like $0801, $0401, $1001, $1c01 instead of $0800, $0400, $1000, $1c00? What is sitting in that one byte, or what role is it playing? I realize that I've always taken that for granted, but never asked myself why. Or I knew it at some point in the past and forgot.
