GENERAL SYSTEM REQUIREMENTS
____________________________________________________________________

CPU
HP 9000 Series 700 Workstations ( see http://www.wsg.hp.com/wsg/ ) including models 
712: /60 & /80
715: /33, /50, /64, /75, /80, & /100
725: /50
735: /99 & /125
755: /99

AVAILABLE HARD DISK SPACE

User Environment:150 MB minimum, 250 MB recommended for stand-alone systems.

User + Developer: Environments: 330 MB minimum, 400 MB recommended.

RAM REQUIREMENTS
RAM requirements vary depending upon the user's selection of graphics adapter. NEXTSTEP Release 3.3 supports a maximum of 256MB of memory.

24-bit color: 16 MB RAM Mininum, 32 MB RAM Recommended
8-bit grayscale/color: 16 MB RAM Minimum, 24 MB RAM Recommended

GRAPHICS ADAPTERS
8-bit grayscale or color at a resolution of 1280x1024 on 712 and 715 workstations and 735 or 755 with CRX adapter. Pseudo 24-bit color available on 712 and 715(/64, /80, or /100) workstations. 24-bit color support on 715 (/33, /50, or /75), 735, and 755 workstations requires the CRX-24 graphics adaptor. Release 3.3 supports multiple monitors with some graphics cards for expanded desktop space. 

MASS STORAGE
SCSI hard disk drives, CD-ROM drives, 1/4 inch tape drives, Exabyte tape drives, and DAT tape drives are supported. 1.44 MB floppy disk drive is supported on the 712 workstations. SCSI floppy is not supported on the 7X5 workstations.

KEYBOARD & POINTING DEVICES
PS/2 style keybaords and mice are supported on the 712 workstations and 715 (/64, /80, or /100). HP-HIL style keyboards and mice are supported on 7X5 workstations except 715 (/64, /80, and /100).

PRINTERS
PostScript printers connected via a serial or parallel port. Color PostScript Level II printers are recommended for proper color support.

NETWORKING
Thick, thin, and twisted pair ethernet on board interfaces are supported. Ethernet transceivers may be necessary for installation at particular sites.

SOUND
16-bit audio at 22 and 44 khz is supported.

INSTALLATION
An HP SCSI CDROM is required for installation of NEXTSTEP.
