Info about Alpha Micro 1021, HP terminal, 8" floppy

Any info on these mature computer components? I was looking in a stack of pallet sized boxes at the local computer surplus and I came across a Alpha Micro 1021 computer. It appears to be about 2' by 2' by 1.5' with a series of DB25 connectors on the back. I couldn't move the top box to gain access to the lower box. I couldn't see much more than the exterior. An adjacent box had a Black Box brand case in it with two drives inside one 8" and one 5 1/4". They look like they have a ribbon connector interface to a computer. Another box had a HP 2392A terminal inside. All of these boxes are covered with dirt and crud, I hope no bird droppings, toxoplasmosis is not a disease I want to catch. I may have to take 4-5 hours and dig through all of the boxes to see what's inside. Kind of like looking for buried treasure, lots of dirt and crud before you find the gold. Maybe the smart choice is to offer $20 for the lot, I think they send all of the non PC stuff to China. Any information would be appreciated. If I don't want/need them maybe someone else does. We can work out shipping. Mike McFadden mmcfadden(a)cmh.edu
