I indeed have a large stock of SID chips, and since I have tested all of them, I also have a (not so) large stock of non-working chips. I did not really sort them the way the hardSID guys did, so some in my "dead" pile might have one or two working voices, but I'd be willing to part with them. Just tell me which side you want to display, and I'll mark the other, so nobody will ever try to use them as SIDs any more.
Now before everyone comes running to me wanting to buy whatever chips: SIDs only go together with Catweasels (so currently they won't sell at all, got to wait for the release of the MK4).
Dead SIDs will go for a symbolic value to anyone with no restrictions, let's say 1,- EUR per tube plus actual shipment.
How about a little note on the thing you want to make:
"No live SIDs were harmed in the making of this artwork"
