GL2-2.x
From TechPubs Wiki
GL2-2.x was released in 1986 for the IRIS 1000 and 2000 68000-based SGI terminals and workstations. It is the origin of the EFS system which replaced the AT&T UFS implementation. Replacing GL2-1.x which only ran on the IRIS 1000 series, it was a major improvement forward with TCP/IP stack, improved filesystem, and many other features.
Changes from 1.x
- Rebased on early UNIX System V Release 0 sources from 1983
- MEX was introduced as the sole GUI offering.
- TCP/IP was introduced from 4.2BSD.
- Actual use of the Geometry Engine as intended by SGI.
Known Applications
Early versions of CATIA and CAMP are attested in historical sources, as well as SGI's splot/gplot demos, Pontiac Division Graphics Systems, and such.
