- I found the following in the NextStep 486 FAQ on comp.sys.next.announce,
- and thought it may be of general interest to PC owners. Note that this
- excerpt contradicts MANY of the previous rumours I have heard on the
- net about NeXTStep 486, and makes me think Intel and NeXT have some sort
- of marketing agreement.
-
- BTW, for those who don't know, NeXTStep 486 is an Intel i486 compatible
- version of NeXT System's NeXTStep 3.0 operating system currently used
- only on NeXT computers. See comp.sys.next.announce for more info.

-
- *** Subject: S19. Will NeXTSTEP 486 run on 386 machines?
-
- No. NeXTSTEP 486 uses several 486 specific features that enhance the
- performance of NeXTSTEP. NeXTSTEP 486 will support any true 486.
-
- ____________________________________________________________________________
-
- *** Subject: S20. Will NeXTSTEP 486 run on the Cyrix 486SLC?
-
- No. The Cyrix chip not a true 486.
-
- ____________________________________________________________________________
-
- *** Subject: S21. Will NeXTSTEP 486 run on the future Intel Microprocessors
- in the x86 family?
-
- Of course! NeXTSTEP 486 will not only support them, but will take advantage of
- any performance enhancements available with future Intel CPU's, just as NeXT
- has taken advantage of the 486.
-
- ____________________________________________________________________________
-
- *** Subject: S23. Will NeXTSTEP 486 be able to run Microsoft DOS and Windows
- programs?
-
- Yes. NeXTSTEP 486 will support a DOS and Windows compatibility package. This
- software will allow DOS 5.0 and Windows 3.1 programs to run within a NeXTSTEP
- window. Support will include DOS "Protected" mode and Windows 3.1 "Standard"
- mode (Win-16). Support for Win-32 applications is planned for the second half
- of 1993.
-
- ____________________________________________________________________________
-
- *** Subject: S24. Will DOS and Windows compatibility be included with
- NeXTSTEP 486?
-
- We have not yet announced how this capability will be packaged.
-
- ____________________________________________________________________________
-
- *** Subject: S25. How will my DOS and Windows applications perform under
- NeXTSTEP 486?
-
- Very well. The DOS/Windows compatibility package for NeXTSTEP 486 takes full
- advantage of the 486 microprocessor. Depending on system hardware
- configuration and type of DOS/Windows application, performance should vary
- between 386 and 486 native DOS/Windows performance. In addition, to enhance
- the performance of Windows applications, a MS Windows specific Graphics
- Device Interface (GDI) driver which maps Microsoft Windows calls directly to
- the NeXTSTEP window server will be part of the system.
-
- ____________________________________________________________________________
-
- *** Subject: S26. Is the window I use to run Microsoft Windows applications
- resizable?
-
- Yes. You can set the Windows session to any size you wish up to the maximum
- screen size available to the NeXTSTEP 486 system you are using.
- ____________________________________________________________________________
-
- *** Subject: S27. Will this DOS/Windows compatibility system allow me to run
- several DOS programs at once?
-
- Yes. Since NeXTSTEP 486 is a multi-tasking, virtual memory operating
- environment, several DOS/Windows sessions can be run at once.
-
- ____________________________________________________________________________
-
- *** Subject: S28. Can I cut and paste between DOS/Windows sessions and
- NeXTSTEP applications?
-
- Yes. You can cut and paste text and graphics between DOS/Windows and NeXTSTEP
- applications.
-
- ____________________________________________________________________________
-
- *** Subject: S29. Can I use both DOS and NeXTSTEP 486 partitions on the same
- hard disk?
-
- Yes. NeXTSTEP 486 will support multiple operating systems on the same local
- hard disk. When the system boots, the user can chose to boot another operating
- system (such as DOS) or NeXTSTEP. If the local partition contains DOS,
- NeXTSTEP 486 will be able to access the local DOS partition and read/write
- files to it.
-
- ____________________________________________________________________________
-
- *** Subject: S30. Can NeXTSTEP 486 read and write DOS format floppies?
-
- Of course. Just like all NeXT Computers.
-
- ____________________________________________________________________________
-
- *** Subject: S31. What are the hardware specs for NeXTSTEP 486?
-
- This document describes in general terms, the types of IBM Compatible PC based
- hardware that will be supported by NeXTSTEP 486 in it's First General Release.
- For specific supported configurations please refer to the NeXTSTEP 486
- Hardware Compatibility Guide. For any hardware specification or purchase,
- please contact NeXT for the latest update to this Guide. This overview is
- preliminary, and subject to change as additional PC hardware is certified for
- NeXTSTEP 486.
-
- 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.
