Have you reviewed this doc? I have a linked pair, just can't get to them right now. . .Ill keep an eye on this thread and report back if you are still stuck.
Have you added the extra chips for the printer ports?

3.1 for CPU and 3.0 for S2 sound is needed.
Both machines show the same error?
What size chip did you use when burning S2? I believe the upgrade to sound rom required a 27C080 chip, instead of the 27C040 chip.
I would pull the chips, blank them, verify they are blank, re-download the rom, re-burn, and retry. Good Luck!
Both roms can be found on: ipdb.org
game rom 3.1
sond rom V3.0 (german) -but this works...
From the release notes:
NBA Fastbreak Sound ROM S2 Revision 3.0
5/9/97
This is a 1-megabyte sound ROM, and requires an 8 megabit EPROM
(27C080, 27C8001, etc) to function properly.

Haha. It's awesome to see johnwartjr chiming in, because he's going to be the guy I turn to for EPROMs and junk if I get a second game. I <3 That Pinball Place.
John, what parts of the link kit would you be able to provide, and what else would be necessary?
I'd try the 2nd S2 chip in the 1st game - it's always possible that one of those sound ROMs is a bad burn, but I'd want to rule the board out first.
Those look like they came from Dave Astill, he provides a good product and good customer service - so if the 2nd chip has the same result, it's possible you've got a board problem or a bad ribbon cable.
If you want to send me both sets of boards, I can throw them on my WPC-95 fixture, give them a good test and repair anything that needs repair. The HV section repair is not something that should take half a day, unless the board is hacked to death.
Mot, I could make a linking cable for someone if they need it, I'm certain. I can't test it, but I seem to recall you only need about 3 pins, so I should be able to test a cable with a meter and know that it's going to work.
The other chips you need are readily available - I helped someone source them recently.
You need 2x TL16C550CN
and 2x max7219cng
