The MGR Window System

MGR, sometimes said to be short for “ManaGeR”, sometimes short for “Munger”, is a simple network transparent window system. It was originally developed for the Sun 3 series of workstations by Stephen Uhler and colleagues beginning in 1984 while at Bellcore (later Telcordia, now part of Ericsson) and later enhanced by many others.

The window system ran on many different hardware platforms, at least these: Sun 3/xx workstations running SunOS, which was the the original development platform, Sun SPARCstations (SunOS and then ported by me to Solaris), Intel x86 based PCs (Coherent, Minix, FreeBSD or Linux), Atari ST (under MiNT), AT&T UnixPC (SysV) and the Macintosh.

I had never heard of MGR before, so this was a great read.
