    For the TL866C, you'll run into issues with the power needed to program most legacy EPROMs. I would highly recommend locating genuine Atmel AT28C16 modules. These will work great with your programmer, and they are pin compatible with the 2716 EPROM.

    Considering the hand-made EPROM adapter you already have these should work perfectly (they come preprogrammed according to what one requests) http://www.ebay.com/itm/254439458288

    Will these work? Also how can I erase them if needed. Also my burner only lists Catgalyst(CSA) CAT27C16, & Fairchild or NSC NMC27C16, B, or Q for any 27C16's

    When using the TL866C and , the AT28C16 is electronically erasable in the programmer. Running MiniPro v6.60 or Xgpro v9.00, both of them list the AT28C16 @DIP24.

    As for that particular seller, I'd ask him to take photos of the top and bottom of the chip, and then post the photos here. The experts can determine if they're fakes. Fakes may work, but from personal experience the fakes are one-time programmable, and do not erase.

    Besides eBay, I'd also check the coin arcade game repair web sites for advice and possible sellers.
