All, I recently bought three Rockwell R65F11A FORTH chips from the following listing: https://www.ebay.com/itm/185625244395 Not affiliated with the seller. They took over a month to arrive, but are genuine, and work fine in a perfboard project I'm building! I haven't tested every single I/O bit but it comes up and runs RSC FORTH V1.7 dev ROMs. The chips that I received are not relabeled and have original 1986 markings. Seller accepted an offer of $19/ea from me, but I did buy three. These don't come up very often, and are much more prototype-friendly than the R65F12, which has more I/O lines but is packaged in a QUIP-64. Thanks, Jonathan
