Frage zum Bally Squalk and Talk sound board

[B.Zarr]

Hallo,

bei meinem 8 Ball Champ sind auf dem Squalk and Talk sound board AS-2518-61, Roms vom Typ 2732 verbaut.

Laut Schaltplan wurden 2716 oder 2532 verbaut,

Was hat es mit den 2732 auf sich und wie müßten hier die Jumper eingestellt werden?

Vielen Dank und liebe Grüße

Helmut

Biddeschön:

AS-2518-61/61A/61B Squawk and Talk board:

-- "A" variant added some sort of delayed-power circuit to the speech

chip, presumably to correct odd noises on powerup?

-- "B" variant added in/out signals for Say It Again reverb board,

so only Centaur requires the B variant. (All games after Centaur

shipped with B variant anyway.)

-- If any of U2 through U5 are 4K (2532/9332/2732), then install

jumpers C and E, and remove jumpers A and B. If only 2K chips

(2716/9316) are used, then install A and B, and remove C and E.

-- Original schematic has an error in the jumpering notes for

2532/9332: they neglected to list jumper "D" as needed.
