Chameleon is an extremely user-friendly multipurpose cartridge that can be used without opening the computer. It is just plugged to the expansion port of the C64.

It can also be operated as a stand-alone unit (since it’s basically an FPGA computer like the C-One in a C64 cartridge case), replacing the computer, the floppy drive and the heavy power supply. A docking station providing 4 joystick ports and connectors for an Amiga or C-64 keyboard is available.
