Trilogy Systems perhaps. (It seems they IPO'ed pre-product? Someone on this forum was probably around when this happened.) Trilogy Systems Corporation was a computer systems company started in 1980. Originally called ACSYS, the company was founded by Gene Amdahl, his son Carl Amdahl[1] and Clifford Madden. Flush with the success of his previous company, Amdahl Corporation, Gene Amdahl was able to raise $230 million for his new venture. Trilogy was the most well funded start-up company up till that point in Silicon Valley history. It had corporate support from Groupe Bull, Digital Equipment Corporation, Unisys, Sperry Rand and others. The plan was to use extremely advanced semiconductor manufacturing techniques to build an IBM compatible mainframe computer that was both cheaper and more powerful than existing systems from IBM and Amdahl Corporation. ... In 1983, the company had an initial public offering and raised $60 million. By mid-1984, the company decided it was too difficult to manufacture their computer design. Gene Amdahl stepped down as CEO and Henry Montgomery was brought in as replacement. https://en.wikipedia.org/wiki/Trilogy_Systems https://en.wikipedia.org/wiki/Trilogy_Systems
