[comp.sys.ibm.pc] bus wars & new PS/2 model

richard@neabbs.UUCP (RICHARD RONTELTAP) (09/18/88)

Well, the rumours about clone makers deciding on a new bus turn
out to be valid. Also IBM HAS released new PS/2 model which uses
the 'old' AT bus.
 
The following two articles are from BPS PRESS service. They
don't charge for distribution but (try to) live on advertising,
so I hope BPS won't mind this posting too much.
 
I don't have their phone number handy, but will gladly send more
info on BPS to anyone.
 
So here are the articles

 GANG OF NINE REBELS
 AGAINST IBM STANDARDS
 ---------------------
 
 (BPS) -- In a bold and unprecedented move, nine major computer
clone makers introduced a new computer architecture standard
that departs from and competes with IBM's Micro Channel
Architecture (MCA).
 
 Lead by Compaq Computer, the Gang of Nine comprise the
following clone makers: AST Research; Epson America, Inc.;
Hewlett-Packard Co; NEC Information Systems; Olivetti; Tandy;
Wyse; and Zenith Data Systems.
 
 Endorsing the new architecture standard were also about 50
hardware and software companies, including Microsoft, Intel,
3Com, Amstrad Plc., AT&T Information Systems, Borland
International, DEC, and others.
 
 The new architecture, called the Extended Industry Standard
Architecture (EISA), is a major advance and extension to the
existing PC Industry Standard Architecture (ISA) which consists
of three components: microprocessors (such as the Intel 80386),
operating systems (such as MS-DOS), and the input/output (I/O)
bus or expansion slots.
 
 The higher-performance Intel 80386 microprocessor and more
powerful new operating systems are expected to drive PCs into
new, more demanding user applications, increasing the need to
extend the current ISA I/O bus to full 32-bit capability in the
future.
 
 EISA is designed to meet those future needs.  It delivers
full-function 32- bit address and data bus extensions, which
support memory capacity beyond today's 16-megabyte maximum.  It
also provides both 32-bit, direct-memory access; and 32-bit,
bus-master support.
 
 According to an EISA spokesperson, the EISA bus with current
cards will deliver about the same performance as IBM's MCA and
Apple Computer's Macintosh NuBus, but will be about 50 percent
faster than MCA and NuBus with future cards designed
specifically for the new EISA bus.
 
 Additional features include programmable board set-up for
autoconfiguration of EISA boards and software-aided
configuration of existing ISA switch- programmable and future
EISA boards.
 
 Unlike IBM's Micro Channel Architecture, which will not work
with earlier industry-standard peripherals (expansion boards,
etc.), EISA not only is compatible with existing
industry-standard hardware and peripherals, but also will
accommodate new peripherals and software designed for
high-performance capabilities.
 
 This is the first time that the clone-maker industry has not
blindly followed IBM's lead, but rather taken its own
independent path.  It may well represent the beginning of the
end of IBM's control of the personal computer industry.
 
 On the same day that IBM's rivals announced their new EISA bus
standard, IBM introduced the PS/2 Model 30 286 with its own
AT-style bus.  (See HARDWARE NEWS for details.)
 
 Both IBM-rivals and IBM officials agree that the two different
bus standards will confuse the public.  Which of the two the
public will prefer remains to be seen.

 IBM INTROS NEW PS/2 AT-STYLE PC
 -------------------------------
 
 (BPS) -- On the same day that IBM-rival clonemakers announced a
new, high- performance, AT-compatible bus architecture (see
INDUSTRY NEWS) different from IBM's Micro Channel Architecture
(MCA), IBM introduced its own AT-style computer system.
 
 Designated the PS/2 Model 30 286, it is identical in appearance
to the original Model 30 (except for a front-panel power switch
that is a different color) but is up to twice as fast, and
offers 25 times more memory capacity.
 
 The new computer features the Intel 80286, 10 MHz
microprocessor, Video Graphics Array (VGA) capability, a 1.44
megabyte 3.5-inch floppy drive, and 512K of RAM, expandable to 4
Mb on the motherboard and 16 Mb with memory expansion boards.
 
 It has three AT-style, horizontal expansion slots that can
accommodate only PC-height expansion cards; not the larger
AT-style cards.  It retails for $1,995 without a hard disk, and
for $2,595 with a 20 Mb hard drive.
 
 With the introduction of two news software offerings -- the
PS/2 Report Program Generator (RPG) II Application Platform, and
the RPG II Application Toolkit -- the Micro Channel-based models
will now run all the software written for IBM System/36 systems.
