Hi all, I've just grabbed a copy of the MOS Technology "MOS Microcomputers Hardware Manual", dated January 1976, MOS publication number 6500-10A from http://www.spies.com/~aek/pdf/ . I've already got a (poor quality) reprint of the August 1975 version (publication number 6500-10). Does anyone know what - if anything - was changed in the January 1976 revision of the manual? Is it worth my while printing the newer manual out again and having it spiral-bound? I was going to print out the MOS Programmer's Manual (doc #6500-50A) anyway. Alternatively, does anyone have original copies of these manuals or the Synertek or Rockwell equivalents? An original MOS Hardware Manual and Programmer's Manual would be nice to have around, but I can live with a laser-print or photocopy if need be.
