IF YOU TRY TO USE THE U7LODER APPROACH, IT DOES ENTER INFO INTO
U7 BUT IT DOES A DES ENCRYPTION ON THE SEED KEYS AND THE U7
'KEYS' ARE NOT WHAT YOU HAD WRITTEN INTO THE U20 RAM AT 66D8.

I SPENT SOME TIME TRYING TO FIGURE OUT WHAT THE LOADER WAS DOING
AND FINALLY GOT IT.

RUN THE DESCALC PROGRAM...
   FOR 'K' ENTER 7 HEX BYTES (SEED KEY)
   FOR 'C' ENTER THE ID NUMBER BACKWARDS AND FOUR BYTES OF '00'
   HIT RETURN ..... THE PLAINTEXT RESULT IS THE SAME AS THE ONE
      YOU WILL FIND IN U7 WHEN YOU PULL THE RELOAD (THE 8TH BYTE   
      IS EXTRANEOUS).

NOW.........IS ANYBODY ELSE OUT THERE TRYING TO FIGURE THIS STUFF
   OUT????????
   
LET'S SHARE INFO !
