Changes

== CPC464 version 3 (medium-sized) ==

* 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.
