   Not yet :-(   
      
   This softswitch is the only left for the function of the Transwarp. The   
   code writes 0 or 1 to that address, and nothing else.   
      
   But there are two functions which must be controlled: switch off the   
   EPROM from AE on the Transwarp and switch off write access to that part   
   of the DRAM onto the Transwarp, which is filled with the Apple ROMs.   
      
   When peeking and poking around with the CALL-151 once I had access to   
   write to the area of the Apple ROM code. But I couldn't repeat this   
   situation. I'm working on it :-)   
      
   I think there is a "magic" combination with the switches used for the   
   language card ($C08x).   
      
   The code written by AE is very obscure, IMHO. I disassembled 1.3 and   
   1.4. And my own code which I wrote in 1987 based on 1.3. Unfortunately I   
   didn't find any disk with my sources on it. Until now ...   
      
   Did you find any 16bit code used by an optional 65802?
