I have two files called 'p5' and 'p5.scrambled'.  I believe the former
is the ROM code as it appears to the Apple and the latter is nearly as it
appears on the ROM, except that the data line permutations are already
taken into account. 

Unfortunately I don't have the original HEX-format listing (with the
data lines partially reversed) nor the program to convert between them
any more. 

They're short, so I'll post them.

"Extremism in defense of liberty is no vice, and moderation in pursuit
of justice is no virtue."  But extreme restriction of liberty in pursuit of 
a modicum of security is a very expensive vice.
