Thanks for the reply. I looked more closely at your pix and I did indeed have 2 of the ribbon's reversed! I looked at the pix I had taken of the rottendog 95 board that was in there and tried to match the ribbon orientation that way instead of looking at the numbers printed on the new rottendog 89 board. Instant Display! So one problem fixed! Actually 2, because that seemed to make my machine work again, same as before...no sound, but it works!
Weirdly, I noticed two other things looking more closely at your pic. I did use the new 601 and 602 ribbons pinsound supplied. Since they gave me both, and i found 601 and 602 on the pinsound (and their instructions told me to) i connected 602 to the pinsound. It appears you didn't? Or was that temporary? I pulled it from the pinsound board, didn't seem to matter.
Also, yes i did get the jumper wire harnesses. The 605 i had to modify the one end because the 89 board only has a 5 pin connector to bring the 80/100 v power. I looked things over, saw the 89 board only needed the 80/100 volt, so i pulled those wires from pinsounds new connector, found an appropriate 5 pin female connector and wired it up. That seemed straightforward. Now that i have the ribbons oriented right, it seems like that's resolved.
When i got to the j138 connection however, i noticed my existing board didn't even have anything plugged into it. I shrugged and plugged the new one in as instructed, but had no need for the z connector. While i was trouble shooting that last night, i checked my fishtales (wpc89 sys), it also doesn't have a j138 connected. When i checked the owners manual for both machines they both indicate j138 N/C (not connected i presume). I checked the voltages where j138 plugs into the J3 slot on the pinsound, the 5 volt was good, but i had no 12v. I assume that will probably bite me at some point, but i do get the chimes and the error recording saying my thumbdrive has no files. I also don't see anywhere on my rottendog 89 that there is a place for the j138 connector. What am I missing there?
I have tried downloading that darn pinsound zip file for NBA a dozen times. I never get one that will unzip. I left a message on pinsounds questions page. I presume they've just got a bad file out there. I guess no one has tried to use it yet...seems weird.
But of course, since this me, once i got the ribbons right and the machine fired up, i was going to put the backglass back up to make sure EVERYTHING was working...and it slipped out of my hands and the glass portion shattered into a million pieces all over my playfield! Of course, since it's NBA it's an odd shape of glass and without it the ball/flipper "game" on the backboard is out of commission!
So i have some cleanup to do while i wait for pinsound to get me a clean zip file!
I really appreciate your help on this. Still a little confused on some of the connections, but i assume their could be differences on the driver board for some of these games. The important thing is i have a display back!
