I have an internal Zip100 (mounted in an external case). Wide 
connectors have usually 68 pins, if you need to attach a narrow 
device (8bit) to a wide bus (16bit), you will need to terminate the 
higher 8bit, but that is not the case here. You will need a DB-25 to 
50 pin centronic or 50 pin high density converter or a cable with a 
DB-25 on one end and a 50 Pin connector at the other. 

You might consider a look at adaptecs onlineshop at  
"http://www.adaptec.com/products/datasheets/external_cables.html"
 but be aware that their prices tend to be a bit high. OTOH the 
products are excellent and I have solved "strange" SCSI problems 
by using their cables.
