Newton: System Updates
Article Created: 30 July 1993
TOPIC -----------------------------------------------------------
This article discusses system updates for your Newton.
DISCUSSION ------------------------------------------------------
Newton will support RAM-based system updates. These updates can be
system enhancements or bug fixes. System updates can be
factory-installed or downloaded and installed by end-users. Most
updates use between 8 and 16K of RAM.
To determine if a update is loaded, check the ROM version in the Startup
screen or the Preferences screen. The last digit following the ROM
version denote the number of the system update that is installed. For
example, 1.14 means ROM version 1.1 with update 4. If the last digit is
0, no updates are installed.
RAM-based updates are kept alive by the lithium backup battery. In the
special emergency shutdown state, the update can be kept intact for
about 26 years. To achieve this state, run your Newton with the backup
battery in, no primary battery installed and the Power Adapter plugged
in. When you remove the Power Adapter with the unit on, Newton will
shutdown virtually everything including the system clock. RAM and
RAM-based system updates are maintained, however.
If you restore data to your Newton from a backup, the system update will
remain intact.
You can erase the system updates by:
1) Removing all batteries and all power from your Newton for over 10
minutes
2) Holding the reset button down while turning on the unit, then tapping
OK in the dialog box that asks you if you want to erase all RAM.
