It is a Linux OS, x86 compatible PC in a case that is branded Commodore. Old Amiga specific HW will not work with it, and any running of either C-64 or Amiga programs will require an emulator package (VICE, Amiga Forever, UAE variants, etc) and the respective ROM's and OS disks.
I highly doubt something like a Genlock would work on it via emulation even if it had the proper ports. It's a commodity component PC, and to be fair to C-USA, they do state that.
Scala may work via an emulator, but you can try that on any mainstream machine you may already have with a proper emulator before you buy the VIC.
