EPROM with gold windows.. Where to sell

Nice picture....very pretty chip.

Here is the link (see below) for an EPROM parts supplier selling the same chip shown in your picture.
Price: $6.45/chip (not per pound)

Link: http://www.futureelectronics.com/en/...001-80XF1.aspx

The webpage indicates he has about 800 in stock, so I imagine these chips must have multiple applications that are still relevant (otherwise, why stock so many?)

I found another link for a different supplier selling a closely related EPROM chip (part #M27C4001-12F1 vs your part# M27C4001-80XF1)
Price: $7.69/chip
LInk: http://www.alliedelec.com/search/pro...x?SKU=70014186

I hope this helps to give you some ball-park pricing reference points.
