Absolutely, the ALDs went with the machines, whether sold or 
leased.  The ALDs contained machine specific info for the 
emulators loaded into it, as well as all ECOs applied at the 
factory and in the field.  So, you could have 2 identical 
models at an installation, and there would be TWO ALD carts, 
with serial numbers on them, so they knew which one applied 
to which box.
