I remember a driver returning to the center with a smashed DIAD II. The center manager asked the driver what happened and he said "I dropped it". The center manager asked, "You just dropped it, are you sure?". After the driver replied yes the center manager pulled a DIAD out of the rack, threw it against the cinder block wall in the center and then sheeted a package, baa-blipp. "You dropped it like that Joe?" the center manager asked the driver who just remained slient. The center manager then did it again and sheeted another package, baa-blipp. After the third throw, the driver blurted out..."OK, OK, I dropped and RAN OVER IT".
center manager: "You sure you only ran over it?"
I don't know how DAID II looks like. I've only worked with III and IV but if no. II is nearly as tough as these versions I bet a little bit more has happened to that DIAD. These machines are almost indestructible!
