I have been trying to fix the speech in my Star Wars, and am down to the "swap components randomly" stage. OK, it's only pseudo-random, it is the main speech synth chip. They were used on Star Wars, Paperboy and 720 according to the most high oracle (google). Clay has a TMS5220-CNL on multigame.com listed as being the part for Star Wars, so I guess one of those would work too. Gauntlet used a TMS5220-CNL, dunno what the C designation means. Thanks guys, and I hope to see many of you at the Atlantic Cafe today, 1:00. 325 S. Main. Sean McLachlan MIS Manager LithoFlexo grafics inc. 801.484.8503
