OK, so the presence of that parallel port has nothing to do with imaging copy-protected disks, as I thought? Now that I think about it, maybe some particular nibbling software (mnib or the like) just requires the parallel port, probably for speed reasons or whatever. > However, when coupled with an appropriate cable, > drives equipped with the parallel connector operate several times faster > than even the fastest non-parallel setups.
