Subject: RASTER: tech: Atari System 1 Indy Jones speech missing, music bad?

> Testing an Atari System 1 Indiana Jones And The Temple Of Doom. Appears to play ok, but in self test, the sound CPU is reported good, but on the Speech Chip Test I get no speech. I tried it in MAME and there are speech clips played. Any idea which chip on which board at what location is bad? The other sounds appear to be fine.

forget mame, it's not always acurate.
the speech is generated by a 28pin texas instruments TMS5220

2 things here.
1: indianna was the only sys1 game with speech, so if the boards were originally something else it may be missing.
2: those chips have a nasty habbit of tarnishing and losing legs.
if you find it the legs will probably look black.
when you take it out of the socket, dont be surprised if you leave some of the legs behind.

in these situations i like to replace the socket with a turned-pin type,
then clean the legs on the chip and fit it in a second turned pin socket with small wires soldered between the socket & stubs where the legs fell off.

then plug the 2 sockets together.

others probably have there own methods - this problem is common in starwars boardsets.
