Level 2 System Resources

The minimum configuration for a PC to satisfy the Level 2 specification includes the following items:

A 25 Mhz 486SX microprocessor with 4 MB of RAM
A 3.5-inch high-density floppy disk drive
A hard disk drive with at least 160 MB of disk space
A 101-key keyboard with a standard DIN connector or one that provides identical functionality by using key combinations
A two-button mouse with a serial or bus connector
A MIDI (Musical Instrument Digital Interface) port that includes MIDI Out, MIDI In, and MIDI Thru, and that has interrupt support for input and FIFO transfer
An IBM-style analog or digital joystick (game) port
A color monitor with a display resolution of 640 by 480 pixels with 65,536 colors
System software that offers binary compatibility with Windows 3.0 or Windows 3.1

In addition, the recommended performance goal for the video adapter (VGA+) is 1.2 million pixels per second using 40 percent or less of the CPU bandwidth. The device-independent bitmaps (DIBs) used to measure this performance goal have color depths of 1, 4, and 8 bits, and can use run-length encoding or be unencoded. A second method of measuring the video performance is to deliver 256-color, 320 by 240 pixel digital-video images at 15 frames per second.
