Are you aware of how much you could get for such a system?
Its a generous offer, and one I'd be interested in if it wasn't for the fact I'm in Australia, but bare in mind you'd easily get $500+ for it.
Given the number of people who just hoard, and don't really even use retro machines, along with the number of opportunists who will resell whatever they can get their hands on at a much inflated price I'd be more inclined to put it on eBay or similar (amibay perhaps?).
Might be worth looking into those who offer to take it off your hands just to make sure they're not the sort of person who will look to simply take advantage and try to profit.
That being said, its your gear and you can of course do with it as you please

I'd just hate to see someone who simply wants to profiteer from your generous offer.
