Thomas Christoph from COREi64 has unveiled his final announcement for 2024: the recreation and enhancement of the TurboMaster V3. For those unfamiliar, the TurboMaster V3 is a 4MHz accelerator for the Commodore 64 that plugs into the C64’s cartridge port, increasing its speed fourfold while maintaining excellent compatibility.
This project has been in the works for most of 2024, developed independently alongside other reproduction efforts. Thomas reverse-engineered every chip on the board, including the rare U18MA chip, which plays a crucial role in enhancing the TurboMaster’s functionality with an REU under GEOS via the MasterAdapter.
A significant amount of time was devoted to fine-tuning the project, with numerous improvements made to the board. Thomas also credits the invaluable assistance of two friends who helped with various aspects of his CMD recreations during the year, contributing to a highly productive period.
The TurboMaster V3 supports two CPU options: the original R65C02P4 and the new WDC W65C02S6TPG-14, which is still available for purchase. The new PCB supports both modern, faster SRAM chips and older ones, eliminating the need for outdated components. Additionally, the V3 introduces jumper-configurable options for connecting to the MasterAdapter.
The MasterAdapter itself has been enhanced, making toggling between GEOram and REU more convenient, and removing the need for hard-to-reach jumpers.
For the TurboMaster case, both a metal recreation and a 3D printable version have been designed, staying true to the original’s essence.
Though the TurboMaster V3 isn’t quite ready for release, final revisions to the PCB and the metal case are expected to wrap up in early 2025. The pricing will be affordable, and the MasterAdapter will also be available for an additional cost for those using GEOS. There may even be a caseless version of the TurboMaster V3 for those who prefer to print their own case.
For those interested in joining the waitlist, Thomas encourages private messages via Facebook with personal details (no public posts). Current prototype photos are available, with more expected in January and February once final design work and testing are complete.
