Thomas Christoph from COREi64 has closed out 2024 with an exciting reveal—the recreated and enhanced TurboMaster V3. This 4MHz accelerator plugs into the Commodore 64’s cartridge port, quadrupling system speed while maintaining strong compatibility.
He developed the TurboMaster V3 independently over most of the year, working alongside other hardware reproduction projects. Every chip on the board was reverse-engineered, including the rare U18MA chip, which boosts performance with an REU under GEOS via the MasterAdapter.
Thomas devoted countless hours to refining the design, solving equations, and improving the board’s capabilities. He credits two friends who supported the project, both involved in earlier CMD recreations.
Expanded CPU and SRAM Support
The TurboMaster V3 works with the original R65C02P4 CPU and the modern WDC W65C02S6TPG-14, available brand new. Its updated PCB supports both fast modern SRAM and older SRAM chips, eliminating dependence on outdated components. Jumper-configurable options allow easy connection to the MasterAdapter.
Upgraded MasterAdapter and Case Designs
The MasterAdapter now supports simple toggling between GEOram and REU without awkward jumper access. For the case, Thomas designed a faithful metal recreation and a 3D printable version, giving users flexibility.
Release Timeline and Availability
Final PCB and metal case revisions will wrap up in early 2025. Pricing will remain affordable, with the MasterAdapter available at extra cost for GEOS users. Thomas also plans a caseless version for those who prefer printing their own case.
