System Overview


The LS550 range from Apricot meets all the needs of the technology or cost driven corporate user. Fully specified, with a choice of the very latest Pentium processors, hard disks and advanced memory technology, every LS550 is designed to offer the widest possible choice of price and specification. This ensures that you can put exactly the right model on each desktop, with no limits on processing power, speed, capacity or performance.

High quality business audio is a standard feature, ready to exploit the new technologies of voice messaging and other audio applications. With the in-built CD-ROM the LS550 is also a state-of-the-art multimedia machine, ready to unleash the potential of the latest, most demanding software.

Pentium with MMX technology

The Pentium processor with MMX technology includes all of the features of a standard Pentium processor, plus more. Because of its improvements, you'll get a better, smoother and more realistic multimedia experience. As raw power on its own is of limited value, the main motherboard used in the LS550 system has been designed specifically to cater for the capabilities of these new Intel processors, ensuring maximum performance from every component in the system.

Ready to network

The LS550 computer has a market-leading 3Com PCI Ethernet card already installed and ready to connect. This 3Com PCI 10/100 auto-sensing Ethernet card provides optimum performance with current 10 Mbit/sec networks and guaranteed upgradeability to the emerging 100Mbit/sec network. For corporates with investment in other NIC's, LS550 systems can be supplied without a network card, allowing integration with Token Ring and other networking technologies. Alternatively a standard 10Mbit/s NIC can be provided for BNC or AUI connection.

Easy to manage

All LS550 systems include enhanced manageability as standard. Designed to be fully DMI compliant, each system is supplied with a Windows application allowing a complete inventory of the system to be made - including firmware and software revision levels. Based upon established industry standards for DMI, the supplied application allows co-operation with third-party network management tools; ensuring a simple and cost effective installation into both new and existing company sites.

In addition, each LS550 system is supplied with 'Electronic Fingerprinting'. This allows your choice of information (e.g. company name, department, asset number, etc..) to be permanently recorded within each system, ensuring a permanent record of system ownership to be available.

Sounds good

All except the entry level models incorporate integrated SoundBlaster Vibra-16 audio from the market leader Creative Labs. Coupled with the high speed Sony CD-ROM, you can now have the benefit of high quality business audio through the unit's built-in speaker, or, for maximum quality through external speakers.

Comprehensive Range

The wide range of LS550 models allows you to choose from entry-level network ready LS550E systems to state of the art performance workstations, ensuring that you can select the ideal system to meet your needs.
