NEW in 2020! The First Supercomputer returns featuring a single segment of the module board!

"There's something about the speed of light; It's just hard to get around." ~ Seymour Cray

This item includes a small section of an original Cray-1 module board. This item first appeared in the Second Edition of the Mini Museum. The board was originally part of the Cray-1 Supercomputer installed at the Lawrence Livermore National Laboratory in Berkeley, California. Introduced in 1975, the complete Cray-1 weighed 5.5 tons and was capable of 80 million floating-point operations per second.

As shown, the specimen is enclosed in an acrylic jar and protected by a classic, glass-topped riker box case measuring 4 1/2" x 3 1/2". A small information card is also included.

Please Note: This specimen is offered in a "blind box" style. Color and size of the module board fragments varies widely. We have tried to randomize the order as much as possible, but if you order more than one specimen you may receive a duplicate color though the patterns on the board are likely to be unique.

It is important to note that the boards were removed after the Cray-1 was decommissioned. As a result, some chips pictured have later serial dates since newer boards were installed to replace failed boards over time.

Furthermore, it's also important to note that while Fairchild chips were most often used throughout the Cray-1, in certain circumstances both Motorolla and Fujitsu SRAMs were occasionally substituted in place of the Fairchild 10415FC. 

The item on offer here is only the module board fragment as all integrated circuit chips are exhausted.

LIMITED ITEM: In order to share this item with as many people as possible, we're limiting purchases to just two (2).

About Seymour Cray and the Cray-1

Seymour Cray was a legend in the world of early digital computers. He was also a veteran of past attempts to create large supercomputers:

"If you work in a large corporation it is very hard to keep on one track for 4-5 years. So, I think that building large computers should be done with the fewest possible people. One is perfect, but it can't quite work with one. The next best thing is about 12."

Eschewing the methods of the past, Cray created a new kind of supercomputer company using just four main principles: simplicity, size, discipline, and cooling.

Earlier attempts to create a viable supercomputer involved the use of incredibly complex integrated circuits. The Cray-1 used just three different types of integrated circuits across the entire machine, vastly simplifying the architecture. For cooling, freon circulated through stainless steel tubing bonded between vertical wedges of aluminum fitted between the stacks of circuit boards.

Cray's innovations yielded a machine that was so advanced that a bidding war ensued for the first machine off the line. This made the Cray-1 was the first commercially successful supercomputer and launched the legend that became Cray Research.

The iconic look of the Cray-1 is more than just 1970's aesthetics at play. Everything was thought through to provide advantages in performance.

The columnar design of the cabinet allowed Cray to minimize the amount of wiring between processing stacks, while the cushions ringing the unit covered the enormous power supplies at the base of each tower.
