Source-derived summary

Ithaca InterSystems, Inc., originally Ithaca Audio and often shortened to InterSystems, was an American computer company active in the 1970s and 1980s and based in Ithaca, New York. The company both manufactured microcomputers and peripherals and developed its own software.

History

Ithaca InterSystems was founded in Ithaca, New York, in March 1977 and formally incorporated in April 1978. Steven Edelman, the company's principal founder, incorporated it with two of his friends. For the first two years of its existence, the company was named Ithaca Audio—an homage to Edelman's original business of reselling Hi-Fi audio gear to his fellow peers at his alma mater of Cornell University in the early 1970s. After graduating from Cornell University with a degree in electrical engineering in 1976, he briefly worked as an engineer at NCR Corporation, working at the latter company's microcomputer research and development laboratory before quitting, citing disagreement with his managers. Edelmen and two others founded InterSystems with $6,000 in startup capital; its initial headquarters was a small rented space in Sheldon Court, within the Collegetown neighborhood adjacent to Cornell University's main campus. In the summer of 1979, the company leased a 8,300-square-foot building off Hanshaw Road, quickly filling it with manufacturing equipment. By the end of 1979, InterSystems had 34 full-time employees on its payroll.

InterSystems' first complete computer system was the DPS-1, a Z80-based, S-100 bus microcomputer, released in 1979.

Editorial reviewMost valuable as an event-and-institution map that identifies actors, dates and record creators for deeper historical inquiry. The current lead gives the account dated anchors—1977, 1978, 1976, 1979—that can be checked directly. The linked authority record independently contributes the date 1978-04. For this dossier, Ithaca, InterSystems and American is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “american computer company” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Chronology, provenance and viewpoint should be read together before a broad social or political interpretation is accepted. The source revision retrieved here is dated Apr 2, 2026. The linked authority identifier is Q6094515. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1977, 1978, 1976 and 1979.

Critical limits

Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Compare institutional narratives with records created by participants and affected communities. Dates and formal titles are useful anchors, but not substitutes for context.
