My 8 Ball Deluxe LE sound was working great. Turned off and on and nothing. No sound at all and only getting the initial flicker (even though quite a solid light).

Changed the 6802 and 6810 - nothing
Checked all ROM's in my burner and all verify ok.

So I decided to bypass the 6810 and moved jumper L to K and the board boots up great! But some of the speech was then totally garbled. Not all just some but worked great before.

So logically speaking the issue is with the 6810. Tried a few more and no joy so figured the old socket must be dodgy. Replaced that socket nd moved jumper K back to L but still no joy!!

Any ideas?

and if the issue is related to the RAM why would now all of a sudden some of the speech be garbled when it worked fine before? My understanding is the only difference now is that I'm using the internal memory of the 6802 instead of the 6810... weird???

More info - when bypassing the 6810.

8 Ball - the eight sounds good but "Ball" is distorted.
9, 10, 11, 12 & 13 Ball - are all total garbage!

All other sounds and speech are great. Nice bass sound to them and proper speed on the speech as before...

So possibly to help someone else... My speech issues above basically come in to play with "Player 2" so I guessed it must be something to do with specific data lines.

Even though U7 PIA was passing the boot sequence - I again put another one in and it sorted the garbled speech issue on all Player 2 phrases!

So that's half the mystery solved and the game is working 100% again BUT it still bugs me that when trying the 6810 configuration it won't boot the 1st Flash after putting in a new socket and trying about 6 different new 6810's that pass testing on a spare MPU board...

Thoughts? (I would like to fix that as there is still a fault on the board even though not using that part of the board currently)

Hi Quench - it was on the board when I bought the machine and I never touched it as it worked. I have taken it off now for a spare as jumpered now for the 6802 and working.

It still bugs me though that the 6810 won't boot after replacing the socket (pinned out ok) and multiple chips
