One word: CatWeasel.  Programs are available for Linux to read and write 
virtually any format floppy with a PC.  Even Apple ][, Commodore, TRS-80, 
PDP-11 (RX02 even if you have an eight-inch drive, RX50 for the 5.25), even 
Mac formatted 3.5 inch floppies can be read and/or written.  With xtrs and a 
catweasel your Fedora 8 box can be the fastest TRS-80 ever made.... (yes, I 
still occasionally fire up xtrs to remember just how good modern OS's like F8 
are compared to the old TRSDOS I started with many years ago.)

You want the MK4 card, which isn't too hard to find.  If you wanted an MK3, 
well, I have one that I'm looking to seel now that I have an MK4... :-). See 
http://amigakit.leamancomputing.com/catalog/product_info.php?cPath=42&products_id=206&osCsid=4749689b5aa2256c81e7b077ee67bc5d 
for an order page from amigakit for the MK4.  The card is $123.41US.  If you 
have lots of old floppies to archive, this is the card to have.

The old 96TPI 5.25 inch double-density drives were pretty common on TRS-80's, 
too, in the enthusiast markets at least.  80 tracks and double-sided; 
aka 'quad density'.
