   Porting AppleWorks to a hypothetical V99   
   21 Mar 24 21:14:20   
   
   From: usotsuki@buric.co   
      
   So I've been working with the hypothetical "V9938 EZCGI" emulated in MAME   
   (-sl5 ezcgi9938), and it got me to thinking about the possibility of   
   hijacking the AppleWorks startup, much as with the VideoTerm, to make a   
   version that runs off the V9938 to use *its* 80x24 text mode, instead of   
   that of an 80-column card.   
      
   Obviously we know the VideoTerm was able to be used this way - and I   
   understand the code in question is located in APLWORKS.SYSTEM, so it's   
   going to be very much version-specific any way one cuts it.   
   Pragmatically, 2.1 is the latest version I'm willing to hack on.  The   
   closest thing I have to documentation is an article in Apple Assembly   
   Line, but it's kind-of hazy, so I've been trying to reverse-engineer the   
   same 1.3 they worked from to try to come to a more complete understanding.   
   Theoretically, I can't imagine it requiring too much change - just new   
   pre-init code to set up the V9938 (which I have written and tested) and   
   a way to replace "place this value at this screen coordinate" with a 9938   
   equivalent?
