Here is the background on this Cray Research Designed Golf Driver. This one has the Cray text on it. I don't think very many of these were made with the Cray text. The driver appears to have been used and because this driver was found with the picture shown, it leads me to believe it was used in this co-sponsored 1992 United Way golf charity event. I have the frame which the pictured poster was in and I will include it.The glass apparently broke at some point but is easily replaced. Here is the info I found regarding the design of the club. The commercially available T-920 did not have the Cray text. For The High Tech Duffer, A Cray Designed Club. Here's news that could lead avid golfers to a lower handicap: MacGregor Golf Co. Has introduced the T-920, a golf club made of titanium and designed on a Cray Y-MP supercomputer. MacGregor design engineers, working with Cray Research Inc. Simulated the impact of a titanium driver striking a golf ball at 100 miles an hour--the approximate speed of a normal swing.
The analysis led to such improvements as a larger head, longer shaft, and special corrugated surfaces on the crown and sole of the club to stiffen the structure. A ball hit with this club, when physically tested, traveled, on average, seven yards farther than one struck with a conventional club, says Clay Long, MacGregor's vice-president for research and development. The simulation program can also be used to improve the design of tennis racquets or hockey sticks, says Cray Research's Carlos Marino, director of the industry science and technology group.
