Audio Connectors

The B2000 workstation has audio-input and -output capabilities through external input
and output connectors on the rear panel and through an internal speaker. The sound is
16-bit, 44 kHz (CD-quality).

The audio connectors are standard stereo audio mini-jacks. Hewlett-Packard recommends
using gold-plated plugs available through audio retailers for best quality recording and
playback through the external connectors.

TOC Button

The TOC (transfer of control) button interrupts the system and transfers control from the
default device to an auxiliary device. A transfer of control saves the state of the processor
in Processor Internal Memory (PIM) and begins execution of recovery software at a
nonzero location specified by a special location in Page Zero called MEM_TOC. The TOC
code is protected by a checksum.
