New Image of a Classic
  You're neither an adventurer nor a professional
  thrill-seeker. You're simply an American tourist in
  London, enjoying a relaxing stroll through the famous
  Kensington Gardens. When World War III starts and
  the city is vaporized moments after the story begins,
  you have no hope of survival.Unless you enter
  another time, another place, another dimension!
  Escaping the destruction of London is not the
  end of your problems, but rather the beginning of
  new, more bizarre riddles. You'll find yourself in an
  exotic world teeming with giant fly traps, strange
  creatures, and other inconveniences.
Time and space will behave with their own intricate and mischievous logic.
You'll visit fantastic places and acquire curious objects as you seek to discover
the logic behind your newfound universe.
And if you can figure out the pattern of events, you'll wind up in the New Mexico
desert, minutes before the culmination of the greatest scientific experiment of
all time: the world's first atomic explosion, code-named "Trinity".

Recent discussions on Csa2 about the .nib image format mentioned that
available .nib disk images for Infocom-Activision'sTrinity are corrupted.
Since the game's disks have (as far as I know) never been deprotected,
there are no good .dsk images either. So, the game has not been available
to users of 8-bit Apple II emulators.

NIB- for "nibble-ized". This is a format originally used to transfer protected
software via telecom connections. The bit-copy output of a copier is placed on
two 5.25" diskettes. Images of these are transferred, and the information is
recombined at the receiving end. Today, the recombined data usually becomes
a .nib disk image file instead of a diskette. A .nib image can be transferred via
the internet and is suitable for use on modern 8-bit Apple II emulators such as
AppleWin and Apple Oasis.

Happily, one of the participants in the thread, Greg E. Nelson, supplied
a good description of how .nib images are created nowadays:

"The way you create a disk image now is, a program reads the disk bytes
from half a disk and stores that data on a whole normal disk.  Then it
is repeated for the second half.  These two disks get moved to the other
pc and merged into a nib image using the emulated version of the

This sounded easy enough to be worth trying! TrinityNew_nib.zip is the
result. The zip file includes three .nib disk images and a Text file with a
few hints for playing the game:

Disk1-     Trinity1N.nib
Disk2-     Trinity2N.nib
GameSave-  SaveN.nib
Info-      ReadMe.txt

I tried out the new images on AppleWin; and, with the help of Origin's
Quest for Clues maps and walkthrough, played the game through to its
conclusion in a few hours. It played like the original with no bombs,
messed up dialog, or other such glitches.

Trinity is a solid medium-difficulty adventure which quickly wraps you
in its dream-like atmosphere. The colorful descriptions and sudden
shifts in scenery can be as disorienting as they are entertaining, though.
So, good mapping is a must.

The game originally came with rather sparse support materials which
do not seem critical. Trinity does a decent job of supplying in-play
clues. However, just in case, you can find the InvisiClues here at 
http://www.apple2.org.za/gswv/a2zine/Docs/HintsCheatsCracks/Trinity_InvisiClues.txt .

To start the game, just boot Disk1 and follow the prompts. Using
Drive 2 for the GameSave disk is a good idea because you play
and do quick Saves and Restores with no further swapping.

Have fun!
