This is the first chip I've had issues w/ burning

I have the device set for AM29F040B, and it detects OK.
Can only get it to write at -2 speed, and it goes to 100% but then fails to verify w/ Address=0x00000000, Device=0x10, Buffer=0xf3.

Reading back shows the contents of the chip as received from eBay.

Any ideas on what I might be doing wrong?
