[1] Interlink was founded in 1983 by Lambert Onuma, Fred Wright, Karl Johnson and Greg Thompson, formerly of Digital Equipment Corporation.
The company's first product, called simply Interlink, allowed IBM MVS mainframes to be connected to VAX computers on a DECnet network.
In 1990, Interlink acquired a product called ACCES/MVS from Advanced Computer Communications, which implemented a native TCP/IP protocol stack on the MVS and VM operating systems and within CICS regions.
This product had been ported from the VM operating system, and required expensive and inefficient protocol conversions.
Interlink was able to successfully sell TCPaccess as a more efficient and better-performing alternative, and as late as 1996 it still held 25% of the TCP/IP market on MVS.
