    Cl> Yep, pin 1 is GND (Vss) and pin 20 is +5V (Vcc).   
      
   Thank You, I thought Pin 1 of the 6526's would be GND after I saw what the   
   Anatomy Book showed for identification on all of the other 6526 Pins.

   Sure enuf, they are there, I didn't think of looking in the Index when I   
   noticed the Schematic was missing in the book that I called a Manual instead   
   of a Guide.   
      
   I haven't browsed the pages of that Book for a long, long time.   
   (Not that I think I know it all)      
      
   PRG = Programmer's Reference Guide , When I saw You write PRG up above,   
   I first thought You were writing about a CBM Program.   DUH!   
   I can't think I ever saw that abbreviation for the C=64 book B4, Thanks!

   Also Thanks for the URL's, I'll keep them handy if ever I want to download   
   that 486 Page File of the whole PRG on this XP computer.   
      
   Which brings a question to me:   
   Would anyone know if there is a .PDF Reader Program for the C=64 ?
