It is a special version of the "ATINIT" file, which is automatically
loaded by ProDOS-8 version 1.4 and later if it is present in the root
directory (only if boot P8 directly, not via GS/OS).

I know of at least three versions of ATINIT:

1. The version supplied with the Apple IIe Workstation Card.  This is
   14 blocks.  It contains code to hook the workstation card into ProDOS.

2. The version supplied with the IIgs System Software.  This is 1 block.
   It is held in the *:System:System.Setup directory, and doesn't contain
   any code (just the user name and printer settings).

3. The special one mentioned above.  This is 15 blocks.  It contains
   code to implement the protocols that are missing in the IIgs ROM
   which are required to support printing over an AppleTalk network
   (mainly PAP and some missing functions in the lower level protocols).
   The code is loaded into another bank.  I'm not sure if this version
   also supports the IIe Workstation Card.

The only place I've seen the third version is with Publish-It!, if I
remember right.  I expect it was licensed by Apple for distribution
with programs that are likely to have a need for printing over
AppleTalk from ProDOS-8 (without booting GS/OS) on a IIgs.  I've never
seen it distributed on a system disk, or as a separate product by
Apple.
