the CoCo and PC pinouts are not different, only the OS implementation of the Side Select line is different (aside from the few lines that are not even used by the CoCo controller.) Since the CoCo didn't "support" DS drives, the SS line was used as DriveSelect3 (using 0-3 numbering). Four single sided drives for Basic/RSDOS/HDB-DOS can equal two Double Sided drives, or *any* four sides of three DS drives.
For anyone interested, I have an article on my website with all the gory details of mapping physical drive sides to RSDOS drive numbers. It's in the Technical Info section under Using Double Sided Drives. This information was a cornerstone of my Basic GUI's capabilities.

Those are PC pinouts. I was looking for the CoCo pinouts. The CoCo
cable signals are slightly different, mainly the drive and side
select lines, as far as I remember.
