Dear all,

I'm obviously in the minority here. My signatures don't match the Atari guides using the CAT box.

Sounds like a the problem with your NOP card. Either the one I mentioned in my other post, or some other problem. Is the "unstable signature" led lit or flashing when you take your measurements? I seem to recall seeing incorrect signatures when I used the NOP method.

Granted, i get the same signatures for the mathbox on the vector games but for the rest of the board i get completely different signatures.

This also points to your NOP card, because the mathbox doesn't use any signals from the NOP card when in SA mode. <snip>

Every time I've used my HP 5006, the signatures have matched the Atari documentation.

Ok, thanks. I guess it really is the right one to go after. Is it true that the it reports the same signature as a cat box? I've heard two different stories, so I wasn't sure what to believe :)

Thanks again

As far as I know - any signature analyzer should do fine. The HP 5004A has the most documentation available online as far as troubleshooting video game boards.

I bought the HP 5004a for $100 although you may see it for slightly less on ebay. I got mine simply because most of the documentation on using the Cinematronics exorsizor mentions this particular model.

Just my 2 cents.

I have decided that I should get a Sig. Analyzer. What is the one to get? I keep seeing people talk about the HP 5004A, is that was I should be targeting? I'm sorry if this has been discussed to death already, I just now finally joined this list. Also, what should I expect to pay for one?

Thanks, Jon
