Steve , 

   It's obvious you know and understand 6502 machine language very well :o)  If I send you a source code of a file that I am trying to burn ,  onto a 2732 Eprom ,  for use in my II+ ,  do you think you can check it out and see if there are any error lines present?  And if so clean it up so that I will work ,  It was a Crack Rom that was designed by The Jerk and The Catcher  back in the early 80's   ,  basically it BSAVED single loaded warez for the user and did some more advanced stuff ,  but that's basially it .   I just don't know exactly how to Bank Switch two files when burning eproms....
 

Thanks...
