   Re: Porting AppleWorks to a hypothetical

   From: usotsuki@buric.co   
      
   First stage:   
      
   I've drafted up replacements for two functions, BASCALC (1717 in v1.3) and   
   CLREOL (173A in v1.3).  Two more functions, SCROLL (15CA in v1.3) and   
   SCRLLR (unknown location, connected to the function at 165E in v1.3) would   
   need to be written and crammed into the original space, and the JSR $C300   
   (235D in v1.3) routed to additional code at the end of APLWORKS.SYSTEM   
   that would initialize the V9938.   
      
   The code is untested, because patching in the replacements kind-of has to   
   be all or nothing.  I think I can try to make a "universal" patcher that   
   can cover 1.0-2.1 and a V9938/V9958 in any slot (provided that the slot is   
   known at patch time, as without a ROM there's no safe way to identify it).   
      
   If it were up to me, I think I'd add a ROM with console drivers and a font   
   in the C800-CBFF space.  Unfortunately, it's not...   
      
   -uso.
