- Simple wrong. microSPARC by Ti integrates ALL onto ONE dice. Period.
- RTFM!
-
- BTW: some R4000 clones by IDT do much the same.

-
- Right. Some vendors give necessary peripheral interfaces away
- all on a mother board. Why should I pay additionally for SCSI,
- ISDN, UART ?

- Given price/performance ratio a GSX board by SUN is competitive to
- video cards of a PC.

-
- NO. It is the add-on policy. To set up a competitive workstation
- for CAD [best remembered, discussion of last afternoon].
-
- EISA bus, as ISA imposses DMA and thereby paging limit to
- lower 16MByte. [No! Kernel bcopy is NO solution for
- graphics.] T

- SCSI-controller, adequate
- 32 MByte RAM
- Weitek 4167

- Solaris 2.1

-
- Think about how much SUN you may buy for 20000,-- DM,
- if disks and monitor are excluded.

-
- Margins are narrow. In fact the clock doubled chips are a necessity
- for clone markes, as they save them a redesign of their mother boards.
- In fact, most cloners can not afford a board design suitable for 66MHz
- square wave.

-
- Window NT developments are done on R3000, as Olivetti provides a
- special development station for Windows NT at better than usual
- conditions. All I know about Windows NT on 486:
- It is said to be unusable slow. There was one demonstration
- of a beta system some developper here around were attending.

-
- OS/2 development is done by IBM, and IBM told the world, that
- OS/2 is regarded to be an "intermediate step to Distributed Computing
- Environment (DCE)" (Hope to have cited correctly.)
-
- Why should they spend any money they already miss on further
- development?
