Austin Computation Center Lines: 24 The story on the Mac IIx's speed is somewhat incomplete. Here's the info. direct from Apple's AppleGram: The Macintosh IIx is the first CPU from Apple to feature the latest technology from Motorola, a 68030 microprocessor and 68882 math co- processor. This combination improves the performance of most applications by an average of 10 to 15% over the Macintosh II, and the performance of certain floating-point calculations, such as logarithms and trigonometric functions, by up to 200%. Since someone asked about the super drive, here's the relevant info. on that: The Macintosh IIx is the first computer to come equipped with Apple's new 1.4MB floppy disk drive, the FDHD (Floppy Disk, High Density), making it the ideal computer for campuses that want to use Macintosh alongside MS- DOS or Apple II-compatible computers. The FDHD reads and writes to the major 3.5" disk formats: the Macintosh Group Code Recording (GCR) 400K, 800K, and Modified Frequency Modulation (MFM) 1.44MB formats; the Apple II GCR 800K format; and MS-DOS and OS/2 MFM 720K and 1.44MB formats. Using the Apple File Exchange, located on the Macintosh Utilities disk, you can now use your Macintosh IIx to access and share files and information stored on other types of computers within your workgroup. ----Chris
