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 -----Original Message----- From: Techtoolslist [mailto:techtoolslist-bounces@flippers.com] On Behalf Of Tony Jones Sent: Thursday, June 16, 2016 7:19 PM To: John Robertson; Technical Tools Mail List Subject: Re: [Techtoolslist] wanted asteroids Signature-Analysis for the cat box 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.

Atari (and Kurz Kasch) used the HP signatures - so if you are not getting the same results make sure the signatures you have are correct for the game. It is always possible you are looking at Asteroids DELUXE signatures for example...
I am attaching some info that may help.
