I took a look at the Star Wars arcade video game schematics, and I don't see any Am2901 chips (unless they obfuscated it really well). The schematic is interesting if you're into that sort of thing. They use two 6809 processors (one for sound effects). There's also a complex matrix processor built out of TTL chips. It does serial multiplication and division using latches and shift registers and adders and so forth. Then there's a bunch more circuitry to generate the analog signals to produce vectors on the screen. It's like a whole different world compared to how this would be implemented now. http://arcarc.xmission.com/PDF_Arcade_Atari_Kee/Star_Wars/Star_Wars_SP-225_2nd_Printing.pdf http://arcarc.xmission.com/PDF_Arcade_Atari_Kee/Star_Wars/St...
