Launched at Macworld Conference & Expo in August 1988, the product provided the same features as NCSA Telnet, with commercial technical support as its only significant added benefit.
This was to change rapidly over the next few months, and by October of that year, InterCon was showing the product at the first InterOp Expo with new features including a graphical FTP Client (one of the first on the Macintosh) and IBM 3270 emulation.
Over the next 5 years, the product evolved quickly and kept or set the pace for many advanced features, including embedded graphics and multimedia content in email; advanced email automation, filtering, and highlighting; a high-speed web browser; a gopher client; and many minor features and protocols.
tcpCONNECT4 (renamed from TCP/Connect II and with additional features) was a "do-everything suite of TCP/IP applications for Internet or intranet use"[4] that was released in 1996 and had few changes before the company's sale to Ascend Communications.
NFS was used widely in educational environments because it was the key file sharing system for Sun Microsystems's line of UNIX servers.
In 1995, InterCon decided to more directly approach the consumer market with a series of "Shark" branded products; NetShark, WebShark, and MailShark.
[8] InterSLIP[9] and InterPPP[10] were software packages that enabled Macintosh users to communicate over TCP/IP using dial-up lines without having to use an embedded TCP/IP stack.
InterServer Publisher[11] was a web, FTP, and gopher server package designed to run in the background on a Macintosh.
When the initial research for IPv6 was being done, InterCon participated by creating an implementation of the SIPP protocol running on the Macintosh as part of an experimental version of TCP/Connect II.
