Dump of GAL (SR2)

[Atari]

Anybody has a dump of the GAL chip used on these? I think the part number is 315-6090A of the chip and the type of board it's used on is 837-13022.

The chip is faulty (if swapped with a chip from a working board the program runs properly).

Thanks!

I tried reading mine with the brute force dumper. Attached is the CUPL output. It's probably bunk, but worth a try in any case.

Thanks! I'll give it a go if no one has a better image.
