I have also considered selling the units (or parts
thereof) if
 nothing gives. 
If it comes to that, I am quite sure you will find buyers for at least
some of it; heck, for a QBus SCSI interface I'd pony up some cash
myself (and there aren't many things I'd be interested enough in to
more than cover shipping for, especially now that I'm as
physical-space-constrained as I am).
