For those that are NBA link savvy..

I’ve got all new chips as designated/identified in the manual, as well I have built a cable that has pins 1 on both end going to ground, and then the Tx and Rx flipped (pin 2 goes to pin 3, and vice versa). At this point after installing the link setup in u9.29/30 on each game respectively, we still see ‘waiting for link’. I did make the cabling quite long, and the only thought I have at this point is to try shortening it.

Any other thoughts on what I should review?

I did the install the player 1 and 2 respectively on each game via the Utilities menu.

I got given a rough linked header. I don’t have the ability to scan this size of an item, and I’m not sure that the condition is a good starting place. I’ll post photos as soon as I receive them from my partner.

Good thought! I haven’t tried that. I’ll see about what happens when we try this.

It seems you may have found one, 73. I just got these photos from my partner of the header that adorns our NBAFBs at the arcade.

The linked header was a Wonderful gift from a good friend of ours that had routed 2 linked NBAFBs. Of historical note, the game on the right was one of the games that sat under this very linked header when they were originally on route. Naturally I had gotten games on them when they were at that location. Pretty neat full circle NBA action.

Stiff cardboard.. and lots and lots of tape.

I bought the 3.1 G11 and the 3.0 S2 from a reputable source for both.

I really should suspect the cable, and just want to be sure that there aren’t any notable pitfalls. Or if perhaps I have the wrong chips. Both also got:
