Good shout. It's blank - all 00s. Checked several times.
I checked UD7 with the same Arduino sketch and wiring and that reads ok.
Seems to me that I might need a new UD6....is this a fat-fingered possibility with the number of times I have been poking at it with a probe?
And can you point me at the right .bin so I can get a new UD6 from the same person as before?
Thanks.
Colin.

With power on, can you check the voltage on UD6 CS3 (pin 21)? (should be +5V).
When you are looking at UD6 pin 11 (D2) you are also looking at UD7 pin 7, UD8 pin 11, and UD9 pin 11 because all of those pins are connected together.
The fact that you have no activity on the D2 data line when UD6 _CS1 is low is surprising. As I recall, you just about got your Arduino Mega PROM reader working. If it's still lying around, try reading UD6 to see if it is still OK.
