Hey folks,

Anyone have an Air Buster board? Can you dump a GAL chip's contents?

I have one here with a dead PR-501 chip, which is a GAL16V8A-25LP located at J13 on the board. If you have one and can read the contents, it'll help me revive a board.

Or, if you know where to get dumps of the PAL and GAL chips, that'd work too. They aren't in MAME.

Thanks!

This probably won't help you directly, but some info here on dumping PALs with an ABI Board Master:

http://www.arcades.plus.com/paldump.htm

You could also try writing to the owner of the web site to see if he has that board, etc.

Charles MacDonald has also done a lot of work on kit to dump PALs:

Again, this won't help you directly, but it may be the case that Charles has dumped that PAL or know someone who has.

Just some ideas. :)
 
Thanks,

I sent a note off to him. I really don't expect anything from it, but just maybe...
 
I have one, but its in my trailer somewhere still boxed up from my move. Its gonna be be a bit till I can get to it. If you are not in a hurry make a note and ask my in a few weeks. When I get things unpacked I will be sending you a few Neo boards as it is.
 
Thanks!

I appreciate any help in resurrecting this board. Sounds like the PAL may be a common failure point for this one as I received a PM from a member who has a similar issue.

Thanks to Raven, I have a copy of the PAL/GAL chip PR-501 and it works.

I copied it to a replacement chip and put the replacement in the socket I put on his board and it's playing nicely.

Oh, and I fixed his board too. The video screen was filled with sparkles and was flickering badly. The culprit was a physically broken 1K 1/8w resistor right next to the Video RAM. :)

Now I have to find where I packed my board and try the replacement GAL.

I'll post the code here in a bit.

And mine is fixed.

Straightened bent pins on custom surface mount chip at C/D18 and reflowed IC. Replaced bad Z80 at K/L14. Replaced bad EPROM at K/L15. Replaced bad PAL at J13.
 
Don't recall...

Zilog invented the Z80 chip, hence you'll find a shitload of them out there.

I've seen just as many bad NEC ones as I have Zilog so I don't curse a particular manufacturer.

If they do, I hope to get some credit under "Arcadecomponents.com" ;)

That's all I ask.

BTW: Guru has the F1 Super Lap Sega FD chip listed on the wanted page. I'm sending him one for decapping and asked for credit under that name.

Sounds fair to me. I'd email them to ask that they do. :)

Sounds like a great idea - the more the merrier. :)
