Ok, is there a picture of a Micropolis 8 inch anywhere? If so I can 
watch for it. The other oddball is the Miniframe, that box had no drives 
any idea what they might have used for that?

That helps. Couple of boxes of floppies I'll keep an eye out for more 8

Ok. Is there typically other stuff in that box? If I can take the drive 
physically out and take the side skins off it might be light enough to 
get up the steps. I'll bring a set of screwdrivers on the next trip out 
and a nice head mounted lamp....

Finally what would be the priority of bringing out one of the printers? 
They look like LJ1 engines and those were heavy but movable.
