Stardent Computer

1989 - 1991
dead us
kubota corporation sold tractors and combine harvesters, and in 1986 it started buying pieces of american workstation startups instead. two of them, stellar and ardent, were merged into stardent in 1989. the founders of one half sued over the merger and were fired inside two weeks. what was left spent two years as a research department for its investor before closing in november 1991.

Kubota Corporation makes tractors. It made them in 1986 as well, and the yen shock of that year had gone badly for a company whose business was heavy farm machinery sold into a market being opened to imports. The board decided to diversify into computers, and rather than build a division it went shopping in Silicon Valley with a checkbook. In July 1986 it put $19 million into Ardent Computer for 22 percent of the company, and another $25 million followed in August 1988. September 1989 brought $24 million more. That is $68 million into one startup, and the National Research Council later used Kubota as its worked example of a Japanese firm buying its way into American technology.

The startup it bought into had a rival. Both were founded in 1985 and both were chasing the same thing, a machine on a desk that could render three dimensional graphics at speeds that until then had required a room. Stellar Computer was in Newton, Massachusetts, run by William Poduska, who had been in on the founding of Prime Computer and then Apollo Computer and came to this one with a longer record than anybody else in the category. Dana Computer was in Sunnyvale, founded in November 1985 by Allen Michels and Matthew Sanders III, with Gordon Bell as VP of Engineering. Dana had to change its name in December 1987 after discovering a local disk drive company already used it, and became Ardent.

The merger was announced on 30 August 1989 and completed that November. Poduska took the chief executive's chair, Bell became chief scientist, and the combined company was called Stardent. The products were good and expensive: a 1990 model was quoted at $123,400, which looked reasonable only next to a Cray. Sales peaked around $40 million in 1990 and never went higher.

I was seven years old in Turkey when this company existed, which is a distance no amount of research closes. The shape of the thing is legible from here anyway. A graphics supercomputer priced at $123,400 has a buyer list you could keep on one page, and in 1985 two separate companies were founded to sell to it.

Michels and Sanders filed suit against Kubota on 13 July 1990 for $25 million in damages. Their claim was that Kubota had used its financial leverage over Ardent to force the merger in the first place, and was then moving people and technology out of Stardent and into a Kubota unit of its own.

Ten days later the company took its investor's side in public. United Press International reported on 23 July that Stardent's directors had terminated both co-chairmen as employees and officers, effective immediately, after a committee of outside directors found their claims to be without merit. The same board meeting approved a letter of intent with Kubota worth more than $50 million in additional financing over two years, and that letter, in the company's own words, paved the way for a new United States subsidiary called Kubota Pacific Computer to begin operations in Santa Clara with complete manufacturing responsibility for Stardent's products. In August the board removed the two men as directors as well and agreed to sell Kubota a further $60 million of equity.

By the end of that sequence Kubota held sole marketing rights across the Pacific Rim, did all the manufacturing, set the prices Stardent paid, and had rights to every piece of Stardent technology. The National Research Council's 1992 study of US and Japanese semiconductor alliances put it plainly: what remained of Stardent was a research and development laboratory kept alive at its investor's discretion.

In August 1991 Stardent spun its Application Visualization System out into a separate company. Three months later, in news that Newsbytes and the Boston Globe both carried on 6 November 1991, the company announced it would stop operating under the Stardent name altogether. Titan workstation operations went to Kubota Pacific, and a new outfit called GS Computer Services was set up to maintain the discontinued GS machines inherited from Stellar. A buyer was sought for the Vistra line and, by the end of December, given up on; the buyer believed to have walked was Oki Electric. The Globe counted roughly $200 million of investor money gone.

Kubota Pacific became Kubota Graphics and closed in 1994, and its remains went to AccelGraphics, which Evans and Sutherland bought in 1998. What outlived all of it was the visualization software spun off three months before the end, which was never a graphics supercomputer and never needed one. Advanced Visual Systems is still trading at avs.com in 2026.
