Tragedy has befallen Ben Heck, once upon a time he created some awesome levels for Doom and now he wants to revisit them, but he cannot! They reside on an ancient and old media type called 'zip disks', zip drives were made by iomega and came in various sizes from 100mByte up to 1gByte. So to reverse engineer it Ben and Felix are going to find an old computer, an oscilloscope and a parallel port connected zip drive to find out how it talks to one another and make it do their bidding!
