Did you ever Rumba with Wall Data? That host connectivity company is now in the belly of NetManage, which used to sell a TCP/IP stack and application suite, and eventually purchased its competitor, FTP Software, in 1998. So TCP/IP products are out, but 3270 is still in. Has anyone heard lately from Rabbit (3270 gateways), Wollongong (one of the few vendors that offered multiplatform TCP/IP) or TGV ("three guys and a VAX")?
FutureSoft made DynaComm, host connectivity software, and is still in business. It also now makes e-mail and Internet filtering technology. Hummingbird was the premier provider of X Windows and still sells Exceed, NFS Maestro and Host Explorer. But the company now sells "enterprise information management systems" (business intelligence and knowledge management). X, BI and KM: I'm sure there's a pattern there.
The old SMC, based in Hauppauge, N.Y., made NICs (remember National Semiconductor's NE2000 chip?), hubs and switches before buying Western Digital (based in Irvine, Calif.) so it could make its own chips. In 1997, SMC sold its systems business to Accton (Taiwan). SMC (still in New York, but now solely in the chip business) still owns 20 percent of the new SMC Networks, which continues to make everything from NICs to Layer 3 switches to wireless technology in Irvine. It's even retained the Tiger switch brand name.
Asanté is also still in business, selling everything from switches to wireless technology. We once wrote a song parody about that company, sung to the tune of "The Slinky Song" and performed at our annual awards show. It went something like this.
