Dillo is a minimalistic web browser particularly intended for older or slower computers and embedded systems. It supports only plain HTML/XHTML and images over HTTP; scripting is ignored entirely. Current versions of Dillo can run on Linux, BSD, OS X, IRIX and Cygwin. Due to its small size, it is the browser of choice in several space-conscious Linux distributions. Released under the GNU GPL-3.0-or-later, Dillo is free software.
Damn Small Linux (DSL) is a computer operating system for the x86 family of personal computers. It is free and open-source software under the terms of the GNU GPL and other free and open source licenses. It was designed to run graphical user interface applications on older PC hardware, for example, machines with 486 and early Pentium microprocessors and very little random-access memory (RAM). DSL is a Live CD with a size of 50 megabytes (MB). What originally began as an experiment to see how much software could fit in 50 MB eventually became a full Linux distribution. It can be installed on storage media with small capacities, like bootable business cards, USB flash drives, various memory cards, and Zip drives.
