Yup, it's a straight-through cable.  If you want to use more than one 
drive at a time, you'll have to remove some of the drive select pins 
from each drive connector (many Coco drives are hard wired to respond to 
all four drive select signals).  It's the same pinout as a PC floppy 
drive.  I made my own cable by taking the 34-pin header-type connectors 
off of a normal floppy cable and moving the card edge connectors to each
