TGV Software: the class project that opened every door after

“Two Guys and a VAX” — the class project, and the door into Microsoft

About this entry

This is Jonathan Hare's account, with its provenance shown. The person or organization named has not yet claimed or corrected it.

Organization

What this is

A cross-platform, multi-protocol networking company — TCP/IP software bridging Macintosh, PC, Unix and VMS systems. Backed by Technology Venture Investors, where David Marquardt was a general partner and on whose board he served.

It went public and was acquired by Cisco Systems in 1996 for around $115 million — which is why this thread, like so many in this graph, ends at Cisco.

The record

Where this intersects the work

Each entry below carries its own provenance — the source, and how it was processed. That is the condition on which this graph can be extended by anyone without degrading.

The trail exists so that people who were there can reconstruct their own memories, recognize what they helped incubate, and add to or correct the record — or forward the few pages that belong to someone they know.

Spring 1991

The class project

Wyc Grousbeck arranged the introduction to Marquardt and proposed a class project for one of his portfolio companies. Jonathan Hare — in his own words a commune boy — did not know what a venture capitalist was. He had never encountered the concept.

Correction: this record previously identified the company as TOPS, the Macintosh daisy-chain networking product then inside Sun Microsystems. The company was TGV Software, which operated in the same niche and whose board Marquardt sat on through TVI. Hare's recollection of the sector was right and the name was wrong.

Why it mattered that he already knew VMS

TGV bridged Macs and PCs to VAX systems running VMS — which Hare knew intimately, because VAX was the primary environment in the Berkeley engineering departments, alongside DEC's PDP line for real-time control. He had also taken a course on IBM's Systems Network Architecture. He was, unusually for a business student, already fluent in the exact problem.
