I have a speech board that the owner claims is for Space Shuttle. None of the call outs that work match what the manual says. I cannot find a cross reference for the chip numbers that are installed. Also, the manual says U4 should be populated and it is not, unless I am reading the chip locations incorrectly. Is there someplace that shows the OEM numbers for Williams games?

If desired...I do have a few of the system 9 speechboards in storage. But I can't reach them before next weekend. I am willing to ship a board to the USA (I am from Europe) but it won't be cheap I am afraid. Let me know if you would like me to search for them.

Thanks MarAlb but that is not necessary, it was just for a spare, I’m sure we can find one laying around somewhere here.
Do you have or know where a list of Williams ROM numbers and what games they are used in? I have found list for Bally and Stern but have not seen one for Williams games.
As far as I know there isn't a list with speech rom numbers. These numbers are listed in the instruction booklets Williams included with the manuals. They can be found on ipdb.org. There is a list of soundrom numbers on pinwiki I believe. Williams can be quite confusing sometimes labeling many soundroms '12' and it can be a quest to find the correct soundroms and the belonging speech roms.
Quoted from TheWiz:Well, I did find some 2532s, but my programmer won’t do these, I have a TL866. So, still out of luck.
Build the adapter, burn as 2732.
