Doesn't detect the chip, though whether it's the recent addition of this board as a programmer or the unsupported chip I couldn't say.
If there is a similar 4Mbit chip option you'd like me to try let me know. I think it's perhaps similar to the Am29F040B and MX29F040 ships. I've just forced it as those chips, and hexdump shows the resulting image showing as all one's. I'm assuming it's a bad read, but as I don't know what was on it to begin with, I can't be sure. For all I know, the chip is fried.
Grazie, Daniel Fussell
