Pole Position PAL

[cliff_poole]

This is a long shot but does anyone have an image of the fusemap for the PAL located at 7C on an Atari board ?. Mine has a floating output on pin 12 which is a chip select for one of the ROMs.

Sadly it isn't included in the MAME ROMs or source code. The device on my board is a 82S153, I don't think these have a protection fuse.

There's a guy on KLOV who's done it as part of a monumental effort to replicate all of the PP hardware, might be worth a PM to him. Short version is he's looking to build new PP/PP2 boards with all modern hardware. I'm really hoping he pulls it off as keeping a PP2 going is not an easy business.

That is an impressive effort !, just looking at his web page. And Pole Position of all games, this is my first experience of the hardware and it is really complicated

Might be worth having a word with Macro to see if a loaner PAL can get dumped by his ABI pal cracker if you can't fix it from the PP/PP2 guy's work.

82s153 dont have a security fuse so a dump is easily taken.
if someone has a dump of this i dont mind converting it to a gal

Porchy, thanks, thats a great offer and I may well take you up on that if I can get the dump.
I have just joined arcade museum although I am restricted as a new user, I'll let you know how I get on.

Pole Position now lives again

I got in touch with Adam, the guy who is reverse engineering the PP hardware, who very kindly sent me his equations for the PAL. Check out his blog !, it is very impressive what he is doing http://ppclone.blogspot.com/

I then sent the equations to our very own porchy who deciphered them and created a JED file suitable for a GAL16V8. Again, very impressive work, I'd like to say a big public 'thank you', to both Adam and porchy !.

Another one for the old Pals page ?.
