3 Interface Devices and Mass-Storage Drives

Audio Controller

Remote Power-On (RPO) There is a cable from the Remote Start connector, on the network board, to

 

the External Start connector, on the system board. This is used by the

 

Remote Power-On feature (RPO) that is described on page 71. This cable

 

must be routed through the hole in the chassis. Not doing so, and allowing

 

the cable to be routed with the flexible disk drive and IDE cables, will raise

 

the risk of radio frequency interference (RFI) cross-talk.

 

The board is supplied with power, even whilst the rest of the computer is

 

turned off, via a line called VStandby on the External Start Connector. This

 

connector also carries the control lines which the network board uses to

 

turn on the main power supply, and to send or receive other control and

 

status information.

 

When shutdown into its RPO state, the board draws 20 mA, well within the

 

50 mA capability of the special RPO power supply.

Drivers

The board can be configured completely by software (no switches or

 

jumpers need changing). Drivers for the network board are supplied with

 

the computer. At the time of release, these bear the version number T.01.00.

Audio Controller

The Creative Labs CT2970 SoundBlaster 16 audio interface, supplied on some models in an ISA slot, can be summarized as follows:

line-out (stereo) jack: 20 Hz to 20 kHz frequency response, 83 dB signal to noise ratio, 0.2% total harmonic distortion

headphones jack: 2 W PMPO per channel, 32 Ω load

speaker connector: 0.2% total harmonic distortion

line-in (stereo) jack: 15 kΩ, 0 V to 2 V peak-to-peak

CD audio-in connector: 15 kΩ, 0 V to 2 V peak-to-peak

microphone input: 600 Ω, dynamic, 30 mV to 200 mV peak-to-peak

MIDI /joystick interface connector: MPU-401 UART compatible

8-bit and 16-bit stereo sampling: 5 kHz to 44.1 kHz

Creative OPL3 synthesizer: 20 polyphonic voices

typical electrical current: +5 V (250 mA), +12 V (250 mA), -12 V (50 mA)

Vectra VL 5/xxx 5 specifications

The HP Vectra VL 5/xxx was a series of desktop personal computers introduced by Hewlett-Packard in the mid-1990s. These machines were designed for both business and professional environments, making them suitable for a range of applications from basic office tasks to more demanding computing needs. This series played a significant role in HP's efforts to strengthen its market presence in the PC sector during a time when competition was intensifying.

One of the standout features of the HP Vectra VL 5/xxx line was its versatility. The series included various configurations designated by the '5/xxx' nomenclature, which indicated different performance levels and specifications. The performance was driven primarily by Intel Pentium processors, widely acclaimed for their reliability and efficiency. This allowed users to choose a model that suited their specific requirements, whether for everyday tasks or more resource-intensive applications.

In addition to its strong processing capabilities, the Vectra VL 5/xxx featured advanced graphics support, which was critical for visual applications and presentations. Many units in this series came equipped with onboard graphics capabilities that supported a range of resolutions, enhancing the user experience in both standard office environments and more creative settings.

Storage options were another highlight of the HP Vectra VL 5/xxx series. The machines typically featured a variety of hard drive configurations, allowing for ample data storage. Some models included the option for expanding storage through additional hard drives or external devices. Coupled with considerable RAM options, these machines ensured smooth multitasking and efficient performance across various applications.

Connectivity was also a core aspect of the Vectra VL 5/xxx. The systems typically included multiple USB ports, parallel and serial ports, and integrated networking capabilities. This made it easy for businesses to integrate the Vectra machines into their existing infrastructure, facilitating seamless interaction with peripherals and networks.

In terms of design, the HP Vectra VL 5/xxx series presented a robust yet compact form factor, which was ideal for office environments with limited space. Additionally, HP emphasized the reliability and serviceability of these machines, which included easy access to internal components for maintenance and upgrades, thereby extending the product life cycle.

Overall, the HP Vectra VL 5/xxx line offered a balanced combination of performance, flexibility, and reliability, making it a solid choice for organizations looking to leverage computing power for a range of professional applications. The series embodied HP's commitment to delivering quality and innovation in the ever-evolving landscape of personal computing.
