If you are using a Macintosh® without a math co-processor (Mac Plus, SE, Classic, LC, or the basic IIsi), be sure to use the "Aldus Super 3D w/o" application only (the w/o indicates that you’re working without the co-processor).
The other application on your disk, "Aldus Super 3D-68881" requires the math co-processor, which is standard on the Macintosh II, IIx, IIci, IIfx, and the Macintosh SE/30, and available as an upgrade for the Macintosh IIsi. If you try to run this version without a math co-processor, you may get a system error.
You may notice in taking a file from a Mac II with 13" or larger monitor to a machine with a 12" monitor that your model is clipped differently on the smaller monitor. You can adjust for this by zooming out with the camera controls.
Super 3D may require more than the mimimum memory allocation of 736Kwhen running under System 7.0 or displaying models in more colors than your system’s basic setting (thousands on the IIsi or millions with a 24-bit color card). If you are unable to open a file because of an out-of-memory message, please set a larger memory allocation from the Get Info box in the Finder.
