Many years ago, I purchased some white UVEPROMS cheap that look a lot like Intel 2708's from the packaging. The seller thought that they were 1702A's but wasn't sure. The problem is, other than a datecode (7829) on the bottom, they are completely unmarked. I am fairly certain that they were not physically cleaned of their markings. The datecode is in that gray-ish ink and a font that further makes me believe that it's an Intel chip. I have a real 1702A, and with a magnifying glass (only), the dies look extremely similar.
Any ideas? I can program (with difficulty) 2708's, but 1702A's, no, and unmarked, they are nothing but curiosities.
