Nanolinux is a very tiny Linux distribution based on MicroCore Linux with busybox.
It uses Nano-X instead of X11. FLTK 1.3.x is used as the GUI toolkit. The window manager is SLWM.
The following applications are included:
FlWriter text processing program
Sprsht spread sheet program
FLTDJ personal information manager
FlMusic CD player
FlRadio internet radio
FlChat IRC client
Antipaint paint program
Fluff file manager
NXterm terminal emulator
FlView image viewer
Games: Tuxchess, NXeyes, Checkers, Blocks, Mastermind, Sudoku
Mount tool, system statistics
Software package download and install utility
Grub package for hard disk install
OSS sound, Truetype fonts, UTF-8 support
Nanolinux requires a 486 processor and 64 MB RAM to run.
If 64MB are available no swapfile is required.
Nanolinux runs completely from RAM. So after booting you can remove the Live CD and use FlMusic to play music CDs.
The distribution is currently available as an ISO image.
