Here is a 250MB internal Iomega IDE Zip drive made for Dell over years ago.  It has remained in its unopened packaging ever since. 

Iomega's model number is Z250ATAPI and their part number is 30360500.  Dell's part number is 0061VM.

This is a 3.5" internal drive with a black faceplate.  A standard IDE cable and a 4-pin Molex power connector are required.  

I do NOT include any Zip disks or cables.  You will receive only the exact drive pictured here with a 30 day return privilege.
