Hi Jerry, thanks for the information.

I had built several terminators, but being terrible at geometry I always
did something wrong. I have now fixed one of the terminators I built. I
had pins 1 and 40 mixed up, the rest of the terminator is basically a
mirror copy.

Unfortunately I still have the same error.

I have an RX02 drive but no controller yet, so I'll have to continue
investigating in the dark.
