I've tried DSL on my Pentium 166 16 Mb RAM laptop (Extensa 390) and it works!
Now, I'm using this machine to make data adquisition and temperature controlling.
My favorite compiler (and programming language) is FreePascal. I've copied some files from a Debian woody installation to make this work, and it works.
Copied files was:
as (to /usr/bin , from binutils package)
ld (to /usr/bin , from binutils package)
libbfd-220.127.116.11.1.so (to /usr/lib called from as or ld ?)
libvga.so.1 (to /usr/lib )
libvgagl.so.1 (to /usr/lib )
libvga.config (to /etc/vga )
Now I can compile and run all my freepascal/vgalib/data adquisition source code.
