Check Dell out online
XP pretty much is over now however if your planning to run a COM port based plotter on it, then u need additional USB/Com converter (if it will work) and any software like SignLab that has a dongle must be USB based and not parallel.
Drivers for plotters maybe a problem on vista.
Good luck with your search for XP, as I say if Dell doesn’t have it as an option when you customise the options, then you wont find them forsale new.
