Is a ceramic NEC D765D worth anything?
It's soldered on an adapter board for a bus I don't recognize. Other parts on
the board have 1977 date codes.
I pulled it out of a recycle bin, so I have no clue what it belongs to. I assume
it's a floppy controller, seeing as it has two 34-pin headers...
I certainly can't imagine much else a ?PD765 would be used for.
No idea about the value, though.
Maybe to a collector. This is the NEC chip with the long "blind spot"
after the index, so it's sort of limited in utility. The 765AD would
have the modern timing.
