Minimum
Recommended New Workstation Configuration
Computer
Workstation
Processor
Intel chip, 2.25 GHz Pentium 4 or comparable AMD Athlon, Athlon XP
2200 if using Windows XP as an operating system processor minimum.
- FOR
CARTOGRAPHIC DATA USE: 3 GHz processor minimum
Memory DDR
SDRAM - Double Data Rate Synchronous Dynamic RAM
512 MB
expandable minimum.
- FOR
CARTOGRAPHIC DATA USE: 1 GB DDR SDRAM
Ports
One (1) Serial
One (2) Universal Serial Bus-USB, 2.0 standard
One (1) Parallel
One (1) P/S-2 Mouse
One (1) SVGA Video if video is built into system board.
One (1) IEE1394 Firewire port
One (1) Ethernet port if connecting the computer to a networked
printer
I/O bus
PCI. Should have at least four available PCI or shared PCI/ISA slots
after system is configured for delivery.
Video
64 or 128 bit PCI interface SVGA controller. Should come with 16MB
Windows RAM (WRAM) or Video RAM (VRAM), and be expandable. Recommend
the selected device provide MPEG hardware acceleration.
- FOR
CARTOGRAPHIC DATA USE: 64 or 128 bit PCI interface SVGA
controller with 128 MB DDR VRAM.
Audio
Sound Blaster PCI64 sound card or compatible.
DISK DRIVES
AND STORAGE
Hard Disk
Drive
80 gigabytes GB capacity or greater, partitioned into smaller drives
for quicker access time. EIDE enhanced integrated drive electronics
interface that conforms to the ATA/100 specification. Rotational
speed of 7,200 rpm. 4MB cache memory. Consider additional hard drive
space 160GB for online video use, to increase the number of CDs that
can be installed or to allow for electronic files to be stored.
- FOR
CARTOGRAPHIC DATA USE: 160 GB or greater capacity, or network
connectivity that provides the same.
Removable/External
Storage
Do not
assume that new computers have 1.44 MB drives for 3.5" floppy
disks. Many manufactures do not provide these drives unless
specifically ordered. GPO still distributes this format and many
library patrons still use these disks.
DVD Drive
8x minimum, 16x speed recommended. Ensure compatibility with CD-ROM,
CD-R, CD-RW, DVD-ROM, DVD-Rs. Alternatively, a DVD-CD combo: 16x DVD/48x
CD ROM.
- FOR
CARTOGRAPHIC DATA USE: 16x DVD. Single platter or changer
design. Should support all available standard CD formats.
Avoid proprietary I/O designs.
CD-RW Drive
Most new systems now come equipped with a CD-RW drive. Look for
rotational speeds of 24x10x40 write/rewrite/read. Needed for
downloading files too large to fit on a regular floppy or for larger
scale backup. The average user is more like to have a CD reader than
a Zip or Jaz drive. Make sure the drive comes with some sort of
MPEG-2 encoding software.
- FOR
CARTOGRAPHIC DATA USE: 48X24X48X.
PERIPHERALS
Monitor
17" Super VGA-SVGA Multimedia monitor with a dot pitch range
between .22 to .27 mm. Look for a high refresh rate of at least
60MHz. Consider flat panel (15" or larger) for staff or in
public areas with limited space. The dot pitch is not an issue with
LCD monitors but, rather, look for a viewing angle of at least 140
degrees.
