II+ reset vector?

On a reboot request, the CPU does an 'JMP ($FFFC)' into the monitor ROM.  The 
monitor does some hardware initialization and tests to see if the PWREDUP 
($3F4) is valid [Does it equal (Value of $3F3) XOR $A5].  If the byte is 
valid, the monitor does a 'JMP ($3F2)' to the user's reset routine.  
Otherwise, th e monitor continues w/ a system reboot.
