Got a translucent C64U User Up-n-Down Port? Light it up! This device plugs in to the cassette port to create a light show in the user port mount. Two RGB color-changing LEDs extend waves of color through the port to complement the look of your C64 Ultimate.
A cassette passthrough connector allows use of the port with a Datasette or other peripheral without removing the device. A slip-on cover protects the port when not in use, gently held with small magnets. Red spots on the cover provide a reminder that it is magnetic.
As with any peripheral, please be sure to power off the computer before connecting or disconnecting this accessory.
These LEDs are independent, not synchronized with the computer's LEDs or even each other. They provide a pleasing automatic fade across the spectrum of colors.
