Cheers everyone,
 
  I am currently designing some hardware for the mac classic, but require
a little software knowledge in order to code the drivers. What I need to
know is the location of the video display buffer (ie. ScrBuf) for
various RAM configurations (since ScrBuf moves according to RAM size, as I
seem to understand things...)

  The configuration that really interests me is the location of ScrBuf in a
4MB classic, but a table of values would come in handy.

Thanks in advance,
steveh.
