Actually, KAM I've worked on SNA to TCP conversions. Well, actually SNA to TCP REPLACEMENTS which I suppose is a bit different.

SNA is/was an IBM specific proprietary communications protocol that was developed in the 1950s or 1960s. We used it through the 1980s at which point that IBM realized that SNA was a dead end. IBM systems have supported TCP for decades and no one uses SNA except to support legacy devices. I know of a few companies that use SNA to TCP conversion devices because they have expensive printers that only "talk" SNA.

Farmers made the switch from IBM proprietary SNA to the TCP open standard and they similarly moved from old fashioned AT&T phone technology to VoIP. Good for them. Kent was the paper pusher on that project. Good for him.
