Features
The 260 watt power supply is switch-selectable for 115
or 230 Vac at an operating frequency of 50/60 Hz. It is
designed to comply with existing emissions standards
and provides sufficient power for a fully loaded system
configuration.
The system supports a variety of standard PC AT-
compatible peripheral devices. The chassis includes
these peripheral bays:
A 3.5-inch front panel bay for a 3.5" diskette drive
5.25-inch front panel bays for mounting 3 half-
height 5.25-inch peripheral devices: tape drive, or
CD ROM drive (not a hard disk drive)
Internal hard disk drive bays for mounting three
hard disk drives (1" to 1.63" high hard disk drives
only).
The system includes a 3.5" diskette drive installed in a
front panel bay. The drive supports 720 KB and 1.44
MB diskette media.
Each model includes a single processor system board.
The system board offers a "flat" design with the
processor and memory subsystems residing on the
board. Figure 2-3 shows the major components on the
