Probably. I didn't realize Perqs used reasonable sized drives, there's a 
box there I've dug out with what looks like a transparent 8 inch drive 
that I will try to disassemble and get up the stairs next time. Think 
"dungeon" and "Y2" class steps....

Absolutely. I have yet more Perq manuals as well and floppies. Did Perqs 
only use 8 inch disks or should I keep eyes out for 5.25 as well?
