The "MPC" (Multimedia PC) standard was created by the Multimedia PC Marketing Council, which was a working group of the Software Publishers Association (now the Software and Information Industry Association).
CD-ROM drives were just coming onto the market in 1990, and this standard was created to make it easier for consumers to know whether their computer could play games labeled with the MPC logo, if their computer also had that logo.
The term didn't catch on very well and the industry turned away from the term in the late 1990's.
The MPC standard for this game was the first MPC standard (Level 1) that came into being. It was defined as a computer with the following minimum requirements:
- 16 MHz 386SX CPU
- 2 MB RAM
- 30 MB hard disk
- 256-color, 640×480 VGA video card
- 1x (single speed) CD-ROM drive using no more than 40% of CPU to read, with < 1 second seek time
- Sound card outputting 22 kHz, 8-bit sound; and inputting 11 kHz, 8-bit sound
- Windows 3.0 with Multimedia Extensions.
