Welcome to the hyperion wiki!

Hyperion is a branch of Hercules with special properties. One of the unique features it that it implements IBM's SNA Technology. This document explores SNA on Hyperion, using the below SNA README from Hyperion's Github documentation as the starting point. This is written from a server/networking specialist's perspective.

SNA is IBM's early networking technology for mainframes, predating all other inter-connectivity methods which did not yet exist. This mainframe inter-connectivity is achieved by using a network interface known as LCS. This is the LAN Channel Interface, and is equivalent to an ethernet network interface.

The main documentation for implementing SNA is here: https://github.com/SDL-Hercules-390/hyperion/blob/master/readme/README.SNA.md

Documentation and ideas to be posted here later in 2024. This may include using Hyperion with IBM Personal Communications 3270 on Windows 95/2000, Microsoft SNA Server, IBM OS/2 Communications Server, Novell Netware SAA (NWSAA) and others. We will explore simplistic setups using OS/390 with subarea networking, and delve into APPN inter-connectivity.
