This chip is from a cartridge for the Atari 2600. The
board is not mine.
I'm trying to help identify the IC.
It's the PCB of the AtariAge post.
I had already looked in the Texas data book and found nothing.
Then it is almost certainly a custom ROM of some flavor

The thread with the photograph had an Ebay source

doesn't help with function, or with the solder blob jumper purpose (or

match
