GIF320 is a GIF viewer for DEC VT320 terminals:
Thanks to C Powers, who sent on this photo of GIF320 in action on a still-extant VT320, in 2024! Apparently this ancient code still compiles on a modern Ubuntu.
The original README, from 33 years previously, is below.
GIF320 3.0 is a gif file viewer for use with VT-320 terminals. It should be easily portable to any platform as it uses only printf and several other stdio commands; some signal trapping and tilde-globbing is also provided, but can be configured out.
Note that GIF320 uses some obscure character-set definition escape sequences, so if you use a VT-320 emulator or a VT-320 clone, it may not work. It will not work on a 220 or a 420, although the 420 claims to emulate a 320. Unfortunately, I don't have access to a 420, so I'm looking for someone with a VT-420, a manual, and intricate knowledge of escape sequences to hack on one for me and find out why not. Anyone fitting that description out there?
A manual page is provided; if you are running GIF320 on an nroff-less system, a pre-formatted manual page, gif320.txt, is also enclosed.
If you are on a system running VAX/VMS, a Makefile-emulation script VMS-MAKE.COM is provided; see README.VMS for more information.
See config.h for configuration options.
