The circuit board is unique to the CLE. No XG series had TTL flash (since the CLE was the first Minolta to do so) and the metering system is unique to the CLE as well. No XG meters off the curtain. This too means shutters are not interchangable either. The off the curtain/film metering sensor is intergrated with the circuit board. I have attached a photo of a new CLE circuit board that I have and you can see the metering display circuits attached on the left hand site and too the right is the metering sensor that is at the bottom of the camera. Its nothing like that of an XG.
