[Techtoolslist] wanted asteroids Signature-Analysis for the cat box

[tonyhtbsusa]

Tony jones is right 
I can use the centipede for Atari on the asteroids board and they match up
for the program address lines 
But the hp are different 
Atari Ab1 5555
Hp   from peter fyfe ab1 ffff
So if you divide by 3 it works in hex 
The ab2 atari cccc
Hp ab2 8484
It does not work if you divide by 3 in hex 
And ab3 atari p763 
Hp ab3 7f7f
My calculator does not have a "p" on it 

Someone must have this done  
Tony

I don't believe this is true.  Normally you need to divide the clock to use
a HP but get signatures that match the Atari docs,  since the CAT box can
perform a NOP in a single clock.
