[Coco] Y-Cable for CoCoSDC and Sound/Speech Pak?

[Ed Snider]

Yes, and that should be ok since there's no address conflict with these two particular carts.

The issues would be that it's unbuffered, can possibly get noisy, and is pulling a little more
power than one might want to from the cart port (probably ok though).

I'd keep the cable as short as possible and be careful as mentioned.
