- PiKey-10 enables the use of wired USB keyboards and Atari joystick/Sega joypads with the TRS-80 MC-10. It includes a 3D-printed riser that is installed between the MC-10's case halves to provide room for such enhancements.
- CoCoVGA is an enhancement for 6847-based systems such as the Color Computers 1 and 2 and MC-10. It outputs VGA, supports all of the graphics and text modes of the 6847, and provides some additional features such as 16-color graphics, 64-column text, and software configurable character/tile sets.
