I recently upgraded to a new PC and had these on my old one. My old one was wiped clean and then traded back to gateway. I have these both with keys and all original boxes and manuals. They are not old at all.
Windows XP Pro Upgrade w/ service pack 1- $90obo
Office XP Professional Full Version - $150 obo
Make offers on these and as I said these original holograph cds with all keys and box and manuals. All Trades considered.......
