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

[Frank Thompson]

I just bought a Sound and Speech Pak on e-bay but don't yet have an MPI
(waiting on the next round of mega-mini MPIs from Zipster!)

I've heard vague mention about simple y-cables made with ribbon cable and
the proper IDC edge connectors, but I can't really find any info regarding
if it is really this simple, or if there needs to be some additional
components involved.  I did see some posts (after google searching) that
said the ribbon y-cables are unreliable and to watch out for improperly
pinned cables.

So, while I wait for a real MPI solution, can I use a y-cable for the SDC
and Sound/Speech pak? Can I just crimp on the two edge connectors to a
ribbon and connect those to a 40 pin finger board?
