Ouch, but 2 Perqs out.

Thanks, that helps. Even though these things used switching power 
supplies (the chassis on the 1 there has a big message saying "warning 
switching supply, high voltages inside) they are still a pretty heavy 
component. I'll focus on getting the stuff off the top and getting the 
side bits in the next trip over. Also will be bringing some garbage bags 
to fill with the junk and wreckage that's down there as well, I should 
try to be a good person and clean out some of the techno-muck.

Ok, I think I saw a mouse or two like that, will pick them up next time.

Yep, photos coming in a bit.

Yep, photos coming in a bit.

Ok. There are TV sets and other stuff in the piles, now that I know what 
I am looking for I'll see what's there.

The key item is priority: I'm trying to remove the data first (hard 
drives, floppies, documentation, and those huge box of Perq tapes), then 
the historical/unique stuff, then stuff that is more 
commodity-historical, then the sun rocks if it's worth it. So any 
opinions from the list based on the pictures of "That is really 
important and should be in a museum CZ" will get the priority and the 
limited bandwidth of getting up the steps. :-)
