     The Apple II FAQs as recognized by Usenet news.answers is available on
several sites:

Ground offers pure Text for downloading or Viewing via
  an FTP program ...
  ftp://ground.ecn.uiowa.edu/apple2/Faqs/
 
Text on the ACN Florida, ACN Tarnover, and USA2WUG sites is
 line-length formatted for on-line perusing via Netscape, etc. ...

Or, in HTML at http://home.swbell.net/rubywand/A2FAQs1START.html



     Here is a snip from the File Utilities FAQ which talks about .nib files:

>>
     Some copy protected diskettes can be converted to another kind of disk
image called "NIB" using Saltine's Super Transcopy. SST incorporates Copy II
Plus routines to attempt to produce a nibblized disk image of a 5.25" diskette.
If successful, you have .nib file which can be used like a diskette on some
popular Apple II emulators. The standard length of a .nib file is 232,960
bytes.
<<
     

     Using SST on an Apple II to transform a .nib file back to diskette,
deprotecting the diskette, and then doing a plain .dsk conversion is one
possible route; but, you would need an Apple II.

     Or, (again on an Apple II) you could deprotect your original diskettes and
convert them to .dsk.

     There is a good deal of deprotection info available on the ACN Florida and
ACN Tanover sites. (See the "Game Info" stuff in Csa2GAME.txt or go to
http://home.swbell.net/rubywand/A2FAQs7GAMESITES.html .)

     Probably the single best source for deprotection information is a
Computist magazine collection. Several Computist issues are availble thanks to
Celt's Computist Project. See ...
