I've seen one in the wild before, but the guy didn't want to sell it with
the pile of Lisas I bought from him.  It's possible I have documentation
for it.
Does "more popular" mean sold more units, or does it mean better liked by
  its owners? :-)
 
I'm positive the Disk ][ was better liked by its owners than that glorified
tape drive called the 1541.
  I never had a Commodore 64!  but, I had an MSD drive
for Commodore 64 that
 interfaced with it with IEC? and IEEE488.
 
I sold one of those within the past couple years.
  To be fully complete with the level of esoterics that
he does mention
 would require a LOT more content.  Whereas a good proofread, and rewrite
 of some sections could make it a good reference for many parts.
 
I think it's something the author wrote in one fell swoop, i.e. "everything
I know about floppy disks".
