[Techtoolslist] Bytek Fireman 8x

[Cameron Rector]

Rodger,
  Thanks for the input however, I believe the last address for the 2532 is FFFh. The 2532 is a 32k device arranged as 12bit address 8bit data or 4096x8=32k.
  I'm a little rusty at this but I also think that 7FFh = 2048 and 4096 = FFFh.
   
  With this said; I still think I have something wrong with my A11 signal or signal path.
   
  If you can think of something else, please let me know.

That's OK, the last address in a 2532 would be 07FF, so at 0800 you're 
no longer inside the 2532.

You have the end of buffer set too high, otherwise it would have stopped 
at 07FF.
