A Teensy 4.1-powered drop-in upgrade for Commodore 64 #VintageComputing

Vintage computing enthusiast Ted Fried has released a neat replacement for the MOS Technology 6510 processor at the heart of the Commodore 64 family of computers — taking advantage of the performance available in a Teensy 4.1 microcontroller board to offer a big speed boost to those who find the original a little slow.

“The MCL64 is a MOS 6510 port of my MCL65+ project which is a 6502 emulator written in C running on a Teensy 4.1 which can be used as a drop-in replacement for the Commodore 64 CPU,” Fried explains. “Like the MCL65+ the MCL64 6510 emulation can either be cycle accurate or it can run significantly faster than the original processor.”

If your Commodore 64 needs a little more oomph, the MCL64 can give it a real shot in the arm.

    This is not the first accelerator they have made.
