Using NTK
System Requirements
This book describes the Newton 2.0 operating system. You'll need a PDA which runs the Newton 2.0 OS.
To run this version of NTK (1.6), you need:
- System 7 (or later).
- A Macintosh with a 68030, 68040, or PowerPC processor.
- A serial cable to connect the Newton to the Mac. One probably came with your Newton. (If not, use a Macintosh/Imagewriter II cable, available from an Apple dealer as model M0197--part number 590-0552-A.)
- 32-bit addressing. For older Macintoshes (the Macintosh II, IIcx, IIci, and SE/30) whose ROMs only support 24-bit addressing, you'll need the "Mode32 7.5" extension, which allows 32-bit addressing on those machines. For Macintoshes that support both 24-bit and 32-bit addressing, you can select 32-bit addressing from the Memory control panel (see FIGURE 2.1). Many newer Macintoshes (such as the Power Macintosh) only run in 32-bit mode and do not provide the 32-bit addressing option in the Memory control panel.
Note:
The "Mode32 7.5" extension is available on-line in the Connectix forums on America Online, CompuServe, or on the Internet at http://www.connectix.com
. It can also be ordered from Connectix at (800) 839-3632 or (415) 571-5100.
Caution:
If you are using System 7.5, do not use the outdated "Mode32" control panel; it will corrupt your System Folder. Use the newer "Mode32 7.5" extension instead, because it will run on System 7.5 (and earlier systems).
