   exceeding 64k

   From: muta...@gmail.com   
      
   With recent (approx a year ago) enhancements to   
   SubC, the text segment exceeded 64k, and since   
   SubC only supports small memory model for DOS,   
   that meant that DOS stopped being self-hosting.   
      
   The solution is to move to medium/large, but I'm   
   wondering whether anything other than the 8086   
   supported more than 64k of code while still using   
   16-bit registers.   
      
   I know some things like the Commodore 128   
   allow memory to be banked out to access more   
   than 64k, but correct me if I'm wrong, but I assume   
   that means getting the C programmer to add   
   bank-switching code to their program, instead of it   
   being transparent like it is on the 8086 (the compiler   
   takes care of generating segment loads).   
      
   And I know that "overlays" exist, but once again it is   
   something the programmer needs to be involved in   
   (I think - I don't know much about overlays).   
      
   For a non-kludged solution, is the 8086 all there is?   
      
   Thanks. Paul.
