The S.A.G. Pentium units
have some unique features. Their SCSI Wide hard drives are mounted in removable enclosures that are protected by a locking mechanism. A swinging door protects you from inadvertently turning off or resetting the system. The tower systems are mobile on their four coaster feet.
The Digital Equipment Celebris XL 5120 and the Dell Optiplex DGX
can take an additional Pentium processor for use with OSes that support symmetric processing, such as Windows NT and OS/2. The Celebris XL 5120's processor and cache circuitry are located on a CPU module that connects to the main logic board. You can upgrade the module with another Pentium processor or even with an Alpha RISC processor.
The Compaq Deskpro XL 5120's
keyboard contains an integrated speaker
and microphone, headphone and microphone jacks, and a mouse connector. You can optionally plug the mouse into the rear-panel connector on the system. A volume control is located to the right of the speaker on the keyboard and works with Microsoft Sound System software. The XL 5120 also features an integrated PCI-based Ethernet controller and a processor board that can be upgraded.
The Reason Square 5 LX-TR/IE
features an embedded sound board on its Intel Aladdin series motherboard. A CrystaLake Wavetable upgrade card was included with the system. It adds complete General MIDI and Roland General Synthesizer compatibility to the Sound Blaster Pro and Microsoft Sound System digital capabilities integrated onto the motherboard.
