Yes, it's a 40 pin.

The 68764 or 68766 will work. I see them in the electronics catalogs and
surplus dealers from time to time. These work for all the Commodore
equipment except the Dual floppy drives.

If you buy chips in large enough quantities, you can have anything you
want printed on them. This is probably what Atari did. I will have to
look out for Atari CO-10750 chips.
