[Coco] A new idea for a CoCoSDC expander

[Kandur]

Been looking at his for weeks, while making a Y-cable.
This gave me the idea of using a double ended male edge connector.
If there was a pc board available, I would have bought one.
Weird? Not at all, rather clever. This way you could place
the unit behind or with feet for air flow, on the top of the Coco.
