An Expansion Port Backplane Extender for the Amstrad / Schneider CPC

Add 3 MX4-compatible expansion card slots to your Amstrad / Schneider CPC, without loosing the edge connector.

Key features are:

1. 3 standard MX4 expansion slots
2. Passthrough edge connector
3. Keyhole in edge connector for hardware that requires it (e.g., DKTronics Retro Speech Synthesizer, ...)
4. Wide signal traces for good signal conductivity
5. Extra wide trace for GND and VCC - unlike other backplane expanders for the CPC, LambdaBoard is capable of powering the DDI-1 and DDI-3 without requiring an extra PSU. An extra PSU is unnecessary for 95% of all CPC extensions.
