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

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.

...SPEED KILLS.

I wonder...what is the speed of gravity?

I used to use MOSLO to run MSDOS games very slowly.

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

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.
