* '''Size: ??? x ??? mm'''
* Medium sized mainboard. Same components as previous version, but arranged more tightly. Joystick/stereo moved to left side.
* Can be optionally fitted with Amphenol connectors (instead of Edge connectors, as far as known, this option was never used for the 464). The screw-holes have contacts for optional shielding-plate(this option was used in german Schneider models).
