[Coco] Educate me about Y-Cables

[Joe Grubbs]

Yeah I'm really looking for a small footprint kind of solution so I can use my CoCoSDC alongside the modem or rs232 pak. Otherwise I'd just try to find a full fledged MPI.

I guess I was really thinking something very simple mainly so I could use 1 additional
slot.  Like an SDC along with a real floppy, or sound cart, or RS-232, etc.

I think someone else is working on a new MPI (Retro Innovations?) so I didn’t really
want to get into that at the moment.  Buffering and some DC power from a wall-wart is easy
enough though.  I'll see what I can come up with.
