Chameleon 64

I've just seen this at Vesalia and I would like to know what is possible to make with it exactly. The links in that page don't seem to open. Here's the description:

Chameleon 64

Flickerfixer, REU, Turbo Board (and A LOT more!) for the Commodore 64

Chameleon 64 is an extremely user-friendly cartridge that can be used without opening the computer. It is just plugged to the expansion port of the C64. Everything a C64 user would expect from a multi-function cartridge is there -- plus a lot more, as you can see in the features overview.

The Chameleon cartridge can also be operated as a stand-alone unit (since it's basically an FPGA computer like the C-One or the Minimig in a C64 cartridge case), replacing the computer, the floppy drive and the heavy power supply. When used as a stand-alone unit, a USB power adapter (available separately) or active USB hub can be used as a power source. Even a USB-enabled computer (or LCD TV, DVD players, ...) can be used to power this nifty little cartridge.

Technical data in short:
  • VGA-output with 60 Hz refresh rate or more
  • Turbo function with full 6510 processor compatibility (incl. illegal opcodes)
  • Cycle-exact REU (memory expansion) with 16 MB RAM
  • MMC/SD card slot with MMC64 compatibility and 1541-emulation
  • Connector for PS/2 mouse and PS/2 keyboard
  • Freezer (compatible with Retro Replay)
  • Bright yellow case with blue buttons
  • Battery-backed real time clock (battery not included)
  • IR receiver for CDTV remote control
  • Stereo audio out for stereo SID emulation
  • USB link to a PC for debugging and data transfer
  • Connector for RR-Net (10 Mbit Ethernet)

(image shows prototype version)

The Chameleon 64 cartridge is under constant development. Since it is a re-configurable platform, hardware updates can be installed by updating the flash of the cartridge. This does not require expert knowledge, and it doesn't even require opening the cartridge. All you need is an internet-enabled PC (running Linux or Windows) with a USB port, this lets you perform the update via a USB connection. The special breakout-cable required for this connection is included with Chameleon 64.
