None of these will run on an 8086. One of them may have, but their website
was shut down in hissyfit^W protest over the European software patent vote.
I don't need it to be *nix based. FreeDOS
http://www.freedos.org is
supposed to run on an 8086 but I couldn't find a distribution of it that
would fit on a 720K floppy.
720k floppy and nothing else - I wish you luck, you're gonna need it!
You might be able to put together a floppy set for Freedos ...
different floppies for each task, each one also containing command.com
so the system can return to command prompt.
If we're talking abaout a single (720k) floppy only, 8086 laptop, with
(if it's like one I remember), 1 Mb RAM split between 640k base and
Rom shadow or ramdisk (backed up so long as the battery is good), then
there's not really much you can do with it these days, and floppy-only
config is a lost art.
If it is the one with ramdisk capability, you can get DOS and a small
toolset in there (but you need a restore disk in case you let the
battery fade), and then use the floppy for applications and storage.
