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. Thanks. On Thu, Feb 24, 2022 at 3:44 PM jim stephens via cctalk <

The thread with the photograph had an Ebay source for the part. https://www.ebay.com/itm/151010204380 doesn't help with function, or with the solder blob jumper purpose (or booboo) but can get the part for some amount if they ship to Brazil. On 2/24/2022 10:24 AM, Bill Degnan via cctalk

I have a pretty complete set of TI books, there are no chips that begin with TB-n. There are many chips that start with T, but none that match your chip ID On Thu, Feb 24, 2022 at 1:21 PM Paul Koning via cctalk < cctalk@classiccmp.org> wrote: > > > > On Feb 24, 2022, at 1:16 PM, Brent

Could be speaking ahead of answers here, but TI had an entire internal PN system for their parts in the 70s (I dealt with it in 75) and they did it to stop people from doing component level repairs on such as TI silent 700s.  I don't think there's a common P/N part in those. I couldn't get
