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.”


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
