LambdaBoard Expansion Board Backplane for Amstrad CPC Computers

For Amstrad / Schneider CPC users that require a couple of MX4 slots for modern hardware, but also need to keep the expansion port edge available for retro hardware (i.e., DDI1 disk interface).

Use case:  DDI3 floppy emulator with edge connector, and 1 M4X 4 MB RAM expansion on LambdaBoard connected to my Schneider CPC 464.
