Chorus. Long History, so my memory may be a little vague. Started out as a French university and government research project (similar roots to MachOS from CarnegieMellon). Extremely geared towards a "distributed computing environment." Heavily backed by French government and by large French conglomerates (Alcatel, Thomson, etc). Then they signed an agreement with ATT (who had acquired Unix System labs) to support a Unix API on top of the Chorus kernel. Way back in 1992, when Microsoft was trying to adress the growth in Unix, by defining Windows NT, some ideas were thrown around on using chorus as the kernel and having SystemV API running. There was even an agreement announced between SCG (now ISI) who did the pSOS kernel, to tie up with Chorus for a new OS they called "Aria". the idea was to wrap the Chorus SystemV APIs around the pSOS kernel.

Years later (1998) Sun was shopping for an embedded OS. Alot was going on, for example the Larry Ellison drive for the Network computer, and the whole ides of "thin Clients". Sun was also backing (I think) a company caled "PowerTV" or something like taht for set top boxes. I hear they looked at buying Lynx real time Systems, who makes the LynxOS. The reasons are obvious: LynxOS supports Unix APIs, so would be a great complement to Sun's Solaris. For whatever reason, the Lynx / Sun deal didn't hapen. Instead, Sun bought Chorus. They started out by treating it as an "independant" entity, but most people speculate that they are trying to jump start their embedded expertise by taking advantage of Chorus' people & knowledge. Further, I would guess that they are trying to use this as a basis for porting the Java VM onto the ChorusOS.

My personal opinion: Sun may have wasted their money. I have heard numerous times that the Chorus code was flaky and unstable, mostly R&D level of completion, not productised. The Chorus OS seems to suffer from a lack of an integrated development environment. If Sun would have bought Lynx, that would have been a VERY interesting story. By the way, the chief architect of the LynxOS is Mitch Bunnel, who is a genus, inmho. He also knows the embedded and hard-real-time isues associated with Java very well.

If anybody on the SI Wind thread knows other or else on Chorus, please feel free to add to this.
cheers!

Integrated Systems Acquires SDS

SDS and Diab Data merged to create the No. 1 development tools leader for embedded
software market

SUNNYVALE, CA. July 15, 1999-- Integrated Systems, Inc. (ISI) (NASDAQ: INTS) announced
today that it has purchased the Chicago-based embedded tools company, Software
Development Systems (SDS), a leader in the embedded systems market and supplier of the
popular SingleStep debugging product line. ISI will pay approximately $40 million in stock
and cash for SDS. ISI intends to merge SDS with Diab Data, ISI's current subsidiary that
supplies leading compiler products for embedded software developers. Together, they will
form a new independently operated business to be called Diab-SDS, focusing on supplying
open and innovative development tools to the rapidly growing global embedded market.

ISI will hold a conference call tomorrow morning, Friday, July 16, 1999, at 7:30 am PST to
discuss the SDS acquisition. To participate in the conference call, please dial (415)
228-4950 approximately 10 minutes prior to the start of the call. The confirmation number
for this conference call is 71699. If you have any questions or need additional information,
please contact Elizabeth Moore at emoore@isi.com. No reservation for this call is necessary.

"The formation of Diab-SDS creates a new leader in the embedded tools arena, where Diab
and SDS have been the long-time complementary solutions of choice by a wide range of
customers and partners. This is a great win for the embedded marketplace, giving customers
what they have been requesting for years: a union of the best compiling technology with the
best debugging technology, resulting in more products, better integration and enhanced
world-class support," said Charles M. Boesenberg, president and CEO of Integrated Systems.

"As partners, Diab Data and SDS have worked closely over the years and enjoyed notable
successes," said James E. Challenger, former president and CEO of SDS and newly named
Chief Technology Officer of ISI. "For the dozens of key partners that we've had in common,
such as Motorola Semiconductor Products and other embedded providers, this merger will be
a pleasant and very welcome move, building on a proven commitment to open technology
and a reputation for excellence

Diab-SDS will operate as an independent business, headquartered in Foster City, California.
Diab-SDS tools will continue to be offered with products from a wide range of suppliers,
maintaining the same open business model that Diab and SDS individually had prior to the
merger. The combined revenue of both companies is over $20 million. The business will
have approximately 100 people worldwide, with eight field offices in North America,
development teams in Chicago, Illinois, Sunnyvale and Foster City, California, and
international sales offices in the U.K., Paris, Munich and Tokyo.

The executive management team includes: David Stepner, president of Diab-SDS; Sven
Brehmer, executive vice president and COO; Arthur Orduna, vice president marketing; John
Mezinko, VP of North America Sales; Geoff Revill, VP of European Sales; and Tomas
Evensen, Bob Gable, and Mike Robie as Site Engineering Managers. Diab-SDS will have a
separate Board of Directors, chaired by Charles M. Boesenberg. Other board members
include: Sven Brehmer, James Challenger, Ingvar Larsson and David Stepner. James
Challenger, formerly president and CEO of SDS, will become chief technology officer of ISI.

"The merging of Diab Data and SDS allows us to focus resources on product innovation with
a common technological vision," said David Stepner, president of Diab-SDS. "For the
thousands of customers that we share in common, the immediate and long-term benefits are
highly significant, ranging from an easier and simplified business interface to the promise of
setting new standards in product quality and ease of use."
