Where to Buy 65-Family Parts
See our forum sticky topic, "65xx parts sources, genuine
and fake" which we try to keep up to date. It's many pages long, but I keep editing the head post to be a summary
of the latest information about sources.
There's quite a counterfeiting industry in China, with counterfeit parts showing up on eBay all the time, and hobbyists are
always getting bit. These recycing yards pull parts out of old circuit boards, clean them up, sand the tops, and re-mark
them. See this YouTube video, and
this one. I don't know why they don't just put
the same markings back on, or just leave the markings alone. What happens is you don't get what you think you're
getting. It's best to just buy from authorized distributors. We try to keep our sticky topic above up to date.
