- This is the "Official" list of hardware requirements from NeXT, it was sent to
- me about four days ago by an engineer at NeXT.
-
-
- General Requirements:
-
- CPU - 486 based PC Compatible Computer. This includes 486SX, 486DX,
- 486DX/2. Future Intel Microprocessor designs in the x86 family will
- also be supported. ISA or EISA expansion bus. 486DX and 486DX/2's are
- recommended for better performance.
-
- Available Hard Disk Space - User Environment, 120 MB Minimum.
- Developer Environment, 330 MB Minimum. Larger local disks are
- recommended for stand alone systems.
-
- Graphics:
-
- NeXTSTEP 486's Display Postscript Graphics system supports both
- Grayscale and Color on 486 based PC's. The Graphics Adapter support
- and RAM requirements vary depending upon the user's selection of
- Grayscale or Color.
-
- 2 Bit Grayscale System Support:
-
- Graphics Adapters - Most VESA (Video Electronics Standards
- Association) compatible VGA or Super VGA Graphics Adapters. This
- includes popular Super VGA cards from vendors such as the Orchid,
- ATI, Paradise, Video Seven and Compaq. These graphics adapters will
- be supported at resolutions of 1024x768, 800x600 and 640x480.
- Resolutions at or above 800x600 are recommended.
-
- RAM - Minimum 8 MB, 12 MB Recommended.
-
- 16 Bit Color System Support:
-
- Graphics Adapters - In order to provide adequate performance and
- Color Quality, NeXTSTEP 486 requires High Performance "Workstation"
- style Graphics Adapters. Many new Graphics Systems are being
- introduced that meet these requirements, they include Intel JAWS
- (such as DELL Processor-Direct Graphics), Chips and Technologies
- Wingine, and certain Local Bus Graphics adapters. Depending upon the
- size of available VRAM (Video RAM) resolutions of 800x600, 1024x768,
- 1120x832 and 1280x1024 will be supported. Graphics Adapters designed
- for EISA based PC's are available (such as Compaq QVision 1024/E and
- ATI Graphics Ultra Pro) or being developed, these are currently being
- evaluated for performance and may provide an easy upgrade for
- existing EISA PC's.
-
- RAM - Minimum 16 MB, 24 MB Recommended.
-
- Additional Device Support:
-
- Disk Interfaces - Both IDE and SCSI Hard Disk Interfaces will be
- supported. SCSI adapters from Adaptec and DPT (for both ISA and EISA)
- will be supported, with more to follow.
-
- Pointing Devices - Microsoft and Logitec compatible Bus, PS/2 port
- and Serial mice are supported. In addition certain graphics tablets
- will also be supported.
-
- Printer Support - Any Postscript Level I or II printer connected via
- a serial or parallel port, including the NeXT Color Printer
- (connected via a SCSI port). Support of Non-Postscript printers will
- be available in a future release.
-
- Networking Support - ISA and EISA based Networking Adapters will be
- supported including Ethernet and Token Ring Cards from vendors such
- as SMC (Western Digital), Intel and 3Com. A Networking card is
- optional.
-
- Sound Support - Most popular PC sound Cards will be supported for
- both Playback and Recording. These include PC Sound Adapters such as
- the Sound Blaster, MediaVision Pro Audio Spectrum and Integrated
- Business Audio from Compaq. A Sound card is optional.
-
- ISDN Support - NeXTSTEP 486 will also support high speed digital
- ISDN connections through an ISA add-on card.
-
- Additional Devices - Other popular PC peripherals such as FAX/Modems
- and FAX/Modem add-on cards will be supported.

-
- NeXT have also said specifically that the Cyrix 486SLC *WONT* run NS486 bacos
- it is not a 'true' 486, its just an enhaced 386.
