Files located on this page are for obsolete versions of Inquisitor models that attach to the computer via the old parallel port. These files are compatible with Windows operating systems up through Windows XP. Please note that even though your computer may be using one of these versions of the Windows operating system, the legacy Inquisitor may still not work. For best results, use an older computer with Pentium 2, or Pentium 3 class microprocessor and compatible chip sets.
