it really depends on whether your software is 16 bit software(circa windows 95/98) or 32 bit software (circa windows 2k or xp),...if it is true 32 bit software you should have no problems running it on a windows 7/ 32 bit system which can be found for very reasonable prices,...the plotter should run off of just about any machine that you can find software that uses the correct drivers and functions on,...you might have to upgrade your dongle drivers also,...
