The Mac ROM-inator kit is back in stock! The ROM-inator replaces the stock ROM with 1MB of re-writable flash ROM in a Macintosh Plus, 512Ke, 512K, or 128K – making it possible to do all sorts of crazy customizations! The new kit has an updated default ROM image, with a new boot chime, modified Happy Mac icon, and System 6 ROM disk with a small collection of built-in apps and games. All these defaults can be changed by updating the flash memory. Personalize that old compact Mac, and make it fun again!
