Slowing CPU speed

Hi all, does anyone know where I can get one of those programs that let me play old games that require slower processor speeds on a 1Ghz machine

  1. Dang, I had an original version of Tetris, it was easy to play on my 16MHz laptop. Kind of fun on my 33MHz laptop. Very challenging on my DX2/66. On my P-133, all the blocks would fall in about 2 seconds. On my 933, I don't even see them fall, I start the program and it says I lost, by the time I see the screen the game is done.

  2. ...SPEED KILLS.

    I wonder...what is the speed of gravity?
  3. I used to use MOSLO to run MSDOS games very slowly.

    Here's the text from the readme.txt file:

    MO'SLO DELUXE PAGE 2 of 4


    Mo'Slo Deluxe lets you to slow the speed of your computer from
    0.1-99.9% of normal in 0.1% increments. To use it, you supply the name
    of the program or batch file you want to run slow as a commandline
    argument. Slowness is adjusted with a command line switch. If a
    % switch is not supplied, Mo'Slo Deluxe slows your computer to
    approximate a 4.77MHz PC/XT.

    INSTALLATION

    To install, simply copy moslo.com into a directory that is accessible
    through your system path variable. To find out which directories are
    in your path, simply enter the word 'path' at the DOS command prompt.
    In DOS 6.22 and earlier, C:\DOS is almost always in the path variable.
    In DOS 7 (Win95), C:\WINDOWS\COMMAND is a good choice.

    OPERATION

    Mo'Slo is a program that runs programs. You execute Mo'Slo with
    slowdown percent and your program's filename as command line
    arguments. Mo'Slo then slows your computer and executes your program.

    If you do not provide a filename extension (COM, EXE, or BAT),
    Mo'Slo Deluxe first looks for a matching COM file, then an EXE file,
    then a BAT file in that order. If the program to be slowed is not in
    the current directory, you must type the complete path with the filename.

    For example, if the default directory at the command line is the root
    directory C:\, and your game 'game.com' is in a subdirectory
    'mygames', the following command entered at the DOS prompt will run
    'game.com' at 20.5% normal speed:

    C:\> moslo /20.5 c:\mygames\game.com

    Since many games use other files to keep high scores, bitmaps, etc.,
    it's best to switch to the drive and directory in which the game is
    located before running it. For example, if the program you want to run
    is located on drive D: in the subdirectory 'mygames', and the default
    directory is currently the root of C: (i.e. your command prompt looks
    like 'C:\>'), then you would first switch to drive D:, then change to
    the '\mygames' directory, then run Mo'Slo. Example command sequence:

    d:
    cd \mygames
    moslo /20.5 game.com

    When you exit your program in the normal fashion, you also exit Mo'Slo
    and normal speed is restored. Mo'Slo doesn't stay resident in memory
    and it doesn't alter the system clock.

    PAUSE MODE -- SPEED ADJUSTMENT WHILE RUNNING

    Mo'Slo Deluxe now has a pause mode that allows you to suspend and
    restart your program while retaining its state. You enter and exit
    pause mode by pressing the Scroll Lock key while the Ctrl and Alt
    keys are being held down. While in pause mode the speed percent
    appears in the upper left corner of your screen. You can adjust
    the speed percent using either the plus (+) and minus (-) keys on
    your numeric keypad or the '=' and '-' keys to the right of the
    standard number keys. (Note that some programs will not allow
    the use of the numeric keypad keys -- you must use the standard
    '=' and '-'. Some programs may not allow pause mode at all.)


    STARTING FULL SPEED FOR QUICKER LOAD

    Mo'Slo Deluxe now lets you load programs at full speed and switch to
    slow mode after the program is loaded. To load fast, press the
    Scroll Lock key prior to running Mo'Slo. Then, when your program has
    loaded and you're ready to go slow, press Ctrl + Alt + Scroll Lock
    (hold Ctrl and Alt while you press Scroll Lock) to start the Mo'Slo
    slowdown engine.


    RUNNING IN A WINDOWS DOS BOX

    Mo'Slo Deluxe is designed for use in MS-DOS. It may run your
    program in a DOS box in Windows95, but this will often produce jerky
    operation. If you want to give it try, use a slightly higher percent
    than you use in DOS. If you try to run a program too slow, Windows
    may appear to 'lock up' as the slowed program attempts to load. If
    this happens, try entering pause mode and adjusting the percent
    upward. If that doesn't work, press Ctrl + Alt + Del and shut down
    the task.

    It may take a while for Windows to normalize after exiting a
    much-slowed program. Be patient.

    For best results, exit to DOS (from Windows95, 'Restart the computer
    in MS-DOS mode') before running Mo'Slo.


    MISCELLANEOUS TIPS

    Enter 'moslo' without arguments to display usage instructions.

    On a 'busy' display, the speed percent may be very difficult to see.
    We had to choose between legibility and keeping memory usage low.

    There may be a few seconds delay when starting a program and when
    exiting to DOS or Windows. Count slowly to ten, then start to worry.

    No slowdown program can be guaranteed to work with all software. Some
    old programs take complete control of a system at a very low level.
    Slowing such programs would require a custom utility.

    Other utilities from Dr.David's Super Crispy Software:

    Dr.David's DOS Utilities package -- includes nine programs:

    REND2 -- Rename and/or move files and directories anywhere, combine
    multi-level paths into one directory, move large directory structures
    onto multiple floppy disks, move by date (before and after), archive
    (on or off), file by file prompt, plus additional options.

    DCOPY -- Like REND2 but copies instead of moves. Faster, more compact
    and with more options than XCOPY.

    DED -- Delete files or entire directories with one command. Delete
    matching files throughout a subdirectory path. Date & attribute
    filters, confirmation & zero-overwrite options, and more.

    CATT -- Change file attributes or find files based on current
    attributes and/or date range in one directory or complete paths.
    Hide directories. Show file names, attributes, number of matching
    files and combined size.

    GO -- Give often-used DOS pathnames descriptive names of up to 63
    characters (spaces OK). Transfer to named subdirectories quickly,
    without having to change default drive manually. For names not in its
    list, GO works like DOS's Change Directory command + drive support.

    Waitfor -- Multi-purpose batch file utility. Read keystrokes, set
    alarms, run programs or reboot at specified intervals, build batch
    file menu systems and more.

    KBSET -- Use in your AUTOEXEC or other batch file to set keyboard
    typematic rates and turn the NumLock switch on/off.

    MPATH -- Changes the default path (including drive). If the specified
    subdirectory path doesn't exist, MPATH creates it.

    AutoPark -- Auto-park read-write heads on up to 8 hard drives at
    user-defined intervals. Less than 500 bytes TSR. For older MFM and
    RLL drives that do not self-park.

    PostScript utilities for desktop publishers and service bureaus:

    PSqueezer(tm) -- reduces size of PostScript files containing
    downloaded fonts 90% and more. Plus, PSqueezed files can print more
    than 67% faster.

    PS*x(tm) Professional -- extracts any combination of pages and/or spot
    color overlays from multi-page and/or multi-color PostScript files.

    Available directly from Dr.David's Software, prepaid w/chk or MO.
    DOS Utilities package: all for $25. PostScript utilities: both for $95.
    Add $5 shipping/handling (or specify email delivery) +sales tax in CA.
  4. I think its faster than the speed of light.

  5. hmmmm, perhaps you can try
    <A HREF="http://www.utilitygeek.com/software/cpu/" target="_new">http://www.utilitygeek.com/software/cpu/</A>
    there are lotsa CPU utilities there, and i've seen a CPU slowing utility, most impt they're freeware i think...
    but still, i've never tried them before, so i don't know whether they'd crash your computer or what???
