Are there any other distros that are easy to configure, run on a P166 with 80MB RAM at a pleasant speed, can be booted by floppy as my 380ED wont boot from CD and have good wireless capabilities. A light window manager like fluxbox or icewm would be preffered over gnome or KDE.
Yes, at least one comes to mind.
Get the Debian boot floppies, and install Debian over the net. Use Windowmaker as the desktop. Install KOffice as the Office package and Firefox as the web browser. Use Sylpheed for email. Use xfe for a file manager.
This was perfectly usable for me on a 200mhz MMX with 64MB memory. It didn't fly, but it ran just fine.
The Debian boot floppies may even let you install from CD.
Its likely that doing a similarly minimalist install from Slackware would work as well, but I did not try that.
If you don't like Windowmaker, try Fluxbox in this scenario. I think WM is a lot better to use, and not much slower, if at all. Also consider fvwm.
