   Frank,   
   Right off the bat may I say, "Thank you" for taking the time to post all the   
   great history & info!   
   To me this stuff is just fasinating! :-)   
   A question for you if I may.   
   The model 4 "base model" that I have with 16k of memory? Would it require a   
   lot of mods to upgrade the memory to 64k or 128k?   
   I heard something about a PAL chip being needed or such. Is it overly   
   complicated or even available for that matter?   
      
   Thank you!   
   -Chris
