Have you purchased a new system only to find that your old applications run too fast or die altogether? Mo'Slo can give many old apps new life. Since 1990, Mo'Slo has been a favorite utility for slowing fast PCs to run speed-sensitive programs. Mo'Slo Deluxe and Mo'Slo 4BIZ features:

  • Command-line operation for application-specific slowdown

    Mo'Slois used to slow a specific application or batch file. When you exit the slowed program you also exit Mo'Slo, and previous system speed resumes. Mo'Slo can be used in batch files and Windows shortcuts, and can be called from other applications. Virtual speed is adjustable from 99.9% down to 0.1% of normal in 0.1% increments. Mo'Slo 4BIZ also supports an 'emulation speed' that is relatively constant on various platforms.

  • Extensive hardware and software compatibility

    Slow MS-DOS applications and batch files on Intel-compatible CPUs from 80386 through Pentium 4 & Athlon, on DOS-compatible platforms through Windows ME and 2000 as well as OS/2, Linux and MacOS DOS emulators. Mo'Slo 4BIZ adds a second slowdown method that expands compatibility to include many Windows applications under Windows 95/98/ME.

  • Keyboard speed adjustment with on-screen display

    Adjust slowdown on-the-fly in applications that do not take complete control of keyboard input. Mo'Slo 4BIZ also allows instant ON/OFF of slowdown.

  • 'Quick load' and other options

    Load applications at full system speed with keyboard initiation of slowdown. Mo'Slo 4BIZ also allows timed delay and initiation of slowdown.

  • A tiny memory footprint

    Occupies less than 1200 bytes while running executable files (plus DOS overhead, which varies with system. Mo'Slo 4BIZ uses an additional 720 bytes when keyboard control is enabled.)

Mo'Slo is being used with many popular game and business programs, but there may be some applications that cannot be slowed effectively. This is a commercial product with an evaluation version for download.
