Thanks Mike.
I was aware of this site, but feel it is too big a risk to buy their CD rom (with all the drivers I don't need just to get the one I do), at a substatial cost ($199.00) -- then possibly find it still doesn't get the device working.
Even though it is a great plotter, it is so old that I don't want to risk $200.00 on a chance of getting it to work.
But again, thanks for your reply, I hope someone else may see this and know of an alternate source.
