supports the D2035B, 3.5-inch, 1.44 MB flexible disk drive.It is software compatible with the DP8473, the 765A, and the N82077. It has a 16-byte FIFO, though this is disabled by default. It supports burst and non-burst modes. It provides perpendicular recording drive support. It has a high-performance internal digital data separator (no external filter components are required). It is implemented in low-power CMOS technology. RTC The real-time clock (RTC) is 146818A-compatible. The configuration RAM is implemented as 256 bytes of CMOS memory. Serial EEPROM This is where the default values for the Setup program are held. Keyboard and Mouse Controller The HP Vectra XU 6/xxx PC and HP Vectra VT 6/xxx PC have an 8042-based keyboard and mouse controller. LITTLE BEN Little BEN is an HP application specific integrated circuit (ASIC) that contains the following: • hard and soft control for the power supply • BIOS timer • flash access and protection • Ultra I/O protection • programmable chip selects • glue logic AUDIO CONTROLLER The HP Vectra XU 6/xxx PC and HP Vectra VT 6/xxx PC have a Creative Labs Vibra 16S CT2504 SoundBlaster 16 audio interface integrated on the system board. This has the following specification: • 80 dB SNR • 8-bit and 16-bit stereo sampling from 5 kHz to 44.1 kHz • Yamaha FM OPL3 synthesizer (11 polyphonic voices) • connector for WaveBlaster standard (wave-table synthesizer) board • 3 inputs (1 microphone, 1 stereo-in, 1 CD-ROM) • 3 outputs (1 internal speaker, 2 stereo-out capable of supporting low-impedance headphones) • connector for MIDI /joystick interface (MPU-401 UART compatible). The headphones jack, microphone jack, and volume control are each on the front panel; the MIDI socket, stereo-in (audio) jack and stereo-out (audio) jack are each on the rear panel. The microphone input has an input impedance of 600 ohms and a sensitivity of 30 mV (peak-to-peak) to 200 mV (peak-to-peak). The headphones jack and the stereo-out (audio) jack each supply 2 W per channel into a 4 ohm load, and can thus be used interchangeably. The Windows 95, OS/2 and Windows NT operating systems each have integrated drivers (Creative SoundBlaster 16). The DOS and Windows 3.x operating systems require the installation of HP Menuet drivers.

AUDIO CONTROLLER
The
HP Vectra XU 6/xxx PC
and
HP Vectra VT 6/xxx PC
have a Creative Labs Vibra 16S CT2504
SoundBlaster 16 audio interface integrated on the system board. This has the following
specification:
•
80 dB SNR
•
8-bit and 16-bit stereo sampling from 5 kHz to 44.1 kHz
•
Yamaha FM OPL3 synthesizer (11 polyphonic voices)
•
connector for WaveBlaster standard (wave-table synthesizer) board
•
3 inputs (1 microphone, 1 stereo-in, 1 CD-ROM)
•
3 outputs (1 internal speaker, 2 stereo-out capable of supporting low-impedance headphones)
•
connector for MIDI /joystick interface (MPU-401 UART compatible).
The headphones jack, microphone jack, and volume control are each on the front panel; the MIDI
socket, stereo-in (audio) jack and stereo-out (audio) jack are each on the rear panel. The
microphone input has an input impedance of 600 ohms and a sensitivity of 30 mV (peak-to-peak)
to 200 mV (peak-to-peak). The headphones jack and the stereo-out (audio) jack each supply 2 W
