Travis Smith’s TeensyROM Provides a Wealth of Performance to Your Commodore 64 or Commodore 128

Classic computing fanatic Travis Smith has designed a brand new accent for the basic Commodore 64 microcomputer, and its follow-up the Commodore 128, providing a variety of options in a single Teensy 4.1-powered cartridge: the TeensyROM.

“TeensyROM is a ROM [Read-Only Memory] emulator, tremendous quick loader, MIDI Host [and] Machine, and Web interface cartridge for the Commodore 64 & 128, based mostly on the Teensy 4.1,” Smith explains of his creation. “Compatable with C64 and C128 machines/variants, NTSC and PAL supported.”
