SC-01 Speech Chip Replacement/Emulator (Votrax)
The SC-01 Speech Chip Emulator replaces Votrax speech chips used in various arcade games such as Gorf, Wizard of Wor, Q*Bert and others. The SC-01 was also used on the Apple Mockingboard, Atari Alien Voice Box and similar sound boars for the era as well as games like the Votrax Type N' Talk!
This replacement for the SC-01 can be used to restore missing voice speech to your classic Arcade or Retro Computer as the original SC-01 is basically unavailable and those that are left are unfortunately doomed to fail if kept in use.
