[cctalk] request for 5.25 floppies

I feel a little silly asking this, I hope it is not an overly inappropriate request for this mailing list. But does anyone here in the States happen to have a stack of known-good 5.25 disks they don't want anymore? And more specifically, would it be possible for anyone to image such a disk with a copy of PC-DOS 2.0 or earlier? (and maybe on up to 3.3 or so) The later part is the service that would be more helpful to me. I finally have a drive for an old system that currently uses bubble memory cartridges to boot to PC-DOS 2.0, and so we'd like to see if (using these external drives) it could also boot to a (confirmed legit) image of IBM PC-DOS (and/or very early Microsoft DOS). Or, do we still need some kind of proprietary Sharp DOS image? (in which case, extra blank disk would be good, as I think there are tools on these bubble memory cartridges to initialize disks accordingly). An actual 160KB formatted PC DOS 1.0 would be fantastic to have on hand - but the 180KB slightly later image would be fine also (and then also to experiment how far "past 2.0" that this system might support, if at all). For shipping/delivery purposes, I'm in north Texas. When I got these drives, I then realized I no longer have any 5.25 floppies anymore - and even if I did, then I'm not quite sure how to get the images on there (did anyone ever make a "USB-to-5.25" drive? I have a couple 3.5 versions of those - maybe the power to motor the 5.25 is too much for USB? :D ). Thanks, SteveL
