Hey all..
I ran across this today...
I didn't realize that there are more than one version of the Williams speech board.
There is the standard c-8228 speech board used in Sinistar and various pins...
Then, I came across a C-10717 speech board that looks almost identical with an exception.
The C-10717 speech board has (2) 0-ohm resistors next to the U4 and U5 eprom sockets.
They are jumpers labeled W1 & W2 and the other is W3 & W4.
I couldn't find any documentaion on this but I assume it is to select the type of eprom being used.
Right now, I have jumpers W1 and W3 set and I'm using 2532 eproms (no speech output so far) I'm fearing that I have the jumpers set wrong.
The C-8228 doesn't have these jumpers and only takes the 2532 eproms.
Anyone familiar with this 'other' SPEECH board?
