Jaguar Vs Cognac

The two projects, which aimed to bring RISC technology to the Macintosh, had totally different approaches and resources. Here are some of the main points which put them at the antipodes.

Jaguar had dozens of engineers from the start and was a very ambitious project.
Cognac, at least initially, had a much smaller team. Work started as a stopgap solution to bridge 68k and RISC, later evolved into a “plan B” and then became the only way forward for the Macintosh.

Since the 88k architecture wasn’t compatible with the 68k one, Jaguar engineers chose to start with a clean slate, even tough this meant that there would be the need to recompile all previous software for the Macintosh. This was similar to the IA-64 debacle of Intel’s Itanium , which was humiliated by AMD’s evolutionary way to add 64-bit computing capabilities to the existing x86 architecture.
The Cognac team was much more pragmatic. (more…)

The 88110 CPU and the RISC workstations that never were

At the beginning of the Nineties both Apple and NeXT were planning to unveil new RISC machines, powered by the Motorola 88110 CPU. At that point the Motorola 68000 family, also known as 68k or m68k, was clearly a dead end and it was time to move on.

The MC88110 was part of a new RISC architecture from Motorola, the 88000, dubbed m88k, and looked like the right solution for both businesses, though it arrived a bit late on the market.

Originally called the 78000, to stress its kinship with the 68000, the new architecture promised to outclass the performance of the processors used in top of the line Macintoshes and NeXT workstations. (more…)

The early days of Apple Computer, Inc.

Filed under: People

2017 marks quite a few big anniversaries for Apple.
While most news outlets and users celebrated the first 10 years of the iPhone, on January 3 longtime Apple employee Chris Espinosa reminded us that forty years ago, Apple was incorporated as Apple Computer, Inc.

The April 1, 1976 date which many remember was Apple’s first and acerbic incarnation, when Jobs, Woz, and Ron Wayne formed the Apple Computer Company as a partnership. (more…)

Larry Tesler on PARC and Apple

Filed under: People

On the 9th of November 2011 a group of engineers and other notable people who worked with Steve Jobs talked publicly about the Apple and Pixar founder during an evening organized by The Churchill Club, a Silicon Valley non-profit business and technology forum.

Among them was Larry Tesler, who started as an engineer at Xerox’s famed PARC center, where (among other things) he invented the technique we now use to copy and paste on a computer and then worked for 17 years at Apple as VP of Advanced Tech and Chief Scientist.

I’ve taken the liberty to transcribe (and edit a bit) the very interesting six minutes of the video recording (start at 30:45, or see a clip) where Tesler tells about Apple’s involvement with PARC, its technologies and people.

“Xerox was facing a lot of competition from Asian companies in copiers when their patents expired and one thing they found was that they had a very high manufacturing cost and they were really having trouble competing with these new forces in the market.
At the same time they had Xerox PARC, developing very exciting technologies including the Ethernet, GUIs with windows and improved mice from what existed before. (more…)

Screw Bjarne

In the world of programming languages, Danish computer scientist Bjarne Stroustrup is a very well-known and respected name. Stroustrup has not only been the head of AT&T Bell Labs’ “Large-scale Programming Research” department for many years but he is also the father of the widely used object-oriented C++ programming language, that he officially released in 1983.

At the end of the Eighties Apple developers decided to start supporting the new language in the Mac Programmer’s Workshop (MPW), at the time the official IDE to create Macintosh software.

Screw BjarneThe effort wasn’t without hitches and C++’s logic caused bouts of frustration, vented in some funny ways. Among them was a “Talking Bjarne” application and most of all the production a of a geeky t-shirt featuring a picture of Stroustrup’s head pierced by a giant screw.

According to Landon Dyer, who made the t-shirt, the image was meant to be an irreverent statement around the fact that he thought that C++ was really “screwed up”, although the message which actually came through was a more direct, and liberating, “Screw Bjarne”.

When Stroustrup came to Apple to give a lecture, Dyer gave him one of the t-shirts and apparently the father of C++ wasn’t angry and seemed delighted to have made such a strong impression on Infinite Loop’s developers.
