Mainboard Versions

Added 300 dpi scans of some motherboards PCB's bottom sides and started using tables to organize data a little better.
* 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).

The cooling plate suggests that this CPC 6128 board would be downgraded for supporting the pin-outs of the old gate array. Most bizarre, the /INT resistor, R144, has white coating, seen at lower-left edge of the cooling plate. On 464 boards similar coating is used on VCC2 resistors. Most likely, this board is a homebrew joke, modded to fool other people.<br style="clear|-|[[File:both;">Schneider6128shielding.jpg|160px]] || || '''Shielding as found in german Schneider models'''|-|}
