 1. ACTIVISION/INFOCOM PRODUCT DEMOS

    The Return to Zork CD-ROM includes demos of three of our 
    products:  Simon the Sorcerer, MechWarrior II:  The Clans, and 
    Richard Scarry's Best Neighborhood Disc Ever.

    After you have installed Return to Zork CD-ROM, you will be able
    to start these demos from the Return to Zork CD-ROM game
    directory.

    To see the Simon the Sorcerer demo, type SIMON at the prompt.  
    To end this interactive demo at any time, press the ESCape key.
    Simon the Sorcerer is currently available from Infocom on 
    floppy disk.

    To see the MechWarrior II:  The Clans demo, type MECH2 at the
    prompt.  MechWarrior II will be available on both floppy disk and
    CD-ROM formats early in 1994.

    To see the Richard Scarry's Best Neighborhood Ever demo,
    type RSCARRY at the prompt.  This product and its companion,
    Richard Scarry's Busiest Neighborhood Ever, are designed for
    children ages 3 and up.  These products are the perfect
    introduction to computers for pre-schoolers.  Parents and
    grandparents will delight in exploring these friendly
    neighborhoods filled with familiar Richard Scarry characters with
    their children and grandchildren.  These games will be available
    in early 1994 on CD-ROM for IBM and Macintosh computer systems.

    For additional information on these and other fine Activision
    titles, please contact your local retailer, or in the U.S. call
    1 (800) 477-3650.
 

 2. INSTALLING UNDER 386MAX

    If the 386MAX memory manager is active, the installer may run
    very slowly.  You might want to disable 386MAX before running
    INSTALL.


 3. RUNNING UNDER QEMM 7.0

    Do not use the "UMB" option in the "DOS=" line in CONFIG.SYS.

    Change "LOADHIGH" to "LOADHI" wherever it occurs in RTZ.BAT.

    Adding the "RH:N" option to the "QEMM386.SYS" line in CONFIG.SYS
    may prevent memory problems while playing the game.


 4. RUNNING UNDER DR DOS

    Change "LOADHIGH" to "HILOAD" wherever it occurs in RTZ.BAT.


 5. ADDITIONAL MADECD.EXE COMMAND-LINE SWITCHES

    -L  Move video buffers into XMS or EMS memory.  Using this is
        highly recommended, as it reduces the amount of conventional
        memory required by about 64K bytes.  Using this switch may
        result in slightly decreased performance.


 6. CD SPEED TEST

    For Return to Zork CD-ROM to operate properly, your CD-ROM drive
    must be able to maintain a minimum level of data throughput.  To
    verify CD-ROM drive performance, a utility called TESTCD has been
    provided.

    To invoke the utility, insert the Return to Zork CD-ROM disc and
    type:

        TESTCD x:

    where "x" is the letter of the CD-ROM drive.  TESTCD will
    determine the speed of the drive and report it to you.

    If the reported speed is below 150 kilobytes per second, the
    quality of the walk through movies in the game may be affected.
    In this case, you may prefer to disable these movies.  See your
    Return to Zork CD-ROM user's manual for instructions.

    If the reported speed is below 100 kilobytes per second, the
    quality of the character conversations in the game may be
    affected.


 7. OPENING MOVIE SOUNDTRACK SELECTION

    On certain systems, such as those with poor CD-ROM throughput,
    low processor speed, or slow VGA adapters, you may detect jumps
    in the soundtrack during the opening and final movies.

    To eliminate this problem, run the Return to Zork CD-ROM
    installer and answer "NO" to the question, "Do you want to play a
    digital soundtrack during the opening movie?"  This will cause a
    MIDI soundtrack to be played instead.

 
 8. ADLIB USERS

    Return to Zork CD-ROM requires a sound card that supports digital
    audio as well as music.  As the AdLib card only supports music,
    you will need to add a digital audio card or device to your
    computer system.  We offer the low-cost LifeSize Sound Enhancer, 
    which attaches to your printer port for digital audio.  Please
    contact the customer service number found in your manual for more
    information.

 
 9. ADLIB GOLD USERS

    You may experience clicking or popping sounds while playing
    Return to Zork CD-ROM with this audio card.  Return to Zork
    CD-ROM supports the DigPak sound system which is supported by
    AdLib products.  Please contact the manufacturer of your card to
    determine the availability of updated DigPak drivers.  When you
    receive a new DigPak driver, copy it into the DRIVERS
    subdirectory.


10. ADVANCED GRAVIS ULTRASOUND USERS
 
    Do not use the Sound Blaster emulation driver (SBOS).  The
    drivers supplied with Return to Zork CD-ROM will use your
    equipment directly.

    If you are experiencing divide errors, look for the file 
    VOICEOOH.PAT in the ULTRASND\MIDI subdirectory. If this file is 
    not available, please contact Gravis for a patch update.


11. DISK COMPRESSION UTILITIES

    You may experience difficulty installing or running Return to
    Zork CD-ROM if you use any disk compression utilities such as
    DoubleDisk, Stacker, DoubleSpace, etc.  If you experience such
    a problem, try deleting all the files in the new Return to Zork
    CD-ROM subdirectory (often called \RTZ-CD).  Then run a
    defragmentation program and try installing again.
