Mini IBM PC (working clone!)

Mini IBM PC - working clone. It uses the FabGL VGA module and a 5" color VGA LCD display. The IBM PC is finely emulated at 2x speed (compared with the original one). The emulated graphic card is CGA or Hercules (automatically switching, afaik), the emulated audio is the IBM PC internal speaker. It can be controlled with a PS/2 keyboard and PS/2 mouse.
