Macintosh LC 520: Button Disabler Software (12/93)

A flier named "Update to Getting Started With Your Macintosh LC 520"
describes a control panel called Button Disabler. It disables the
buttons on the front of the Macintosh LC 520, so that students can't
adjust the volume or brightness.

The flier also states that the control panel is already installed with
the system software, but I don't find this control panel.

System Enabler 403 version 1.0 didn't include modifications required
for a Button Disabler control panel. Engineering then received
feedback from customers requesting a way to disable the front buttons.
In order to implement the Button Disabler, they also needed to revise
the System Enabler for the Macintosh LC 520. Version 1.0.1 was
released, which included three new disks -- the Install Me First disk,
the Disk Tools disk, and the Extras disk. If you have System Enabler
403 version 1.0.1, you'll have the Button Disabler.

The documentation for the Macintosh LC 520 couldn't be revised, so a
flier describing the Button Disabler was included instead. This flier
ships with the Macintosh LC 520 computers that have the Button Disabler
software already installed on the computer. A customer shouldn't have
one of these fliers unless they have the Button Disabler and System
Enabler 403 version 1.0.1.
