For PCs that
leaves a few things like BeOS, Minix, DOS,
ConcurrentDOS, CCPM and not much else.
BeOS floppy based? The versions I've seen had larger
requirements than floppies and 4MB RAM. The mention of ConcurrentDOS
I didn't mean to imply they were floppy based only smaller footprint on
disk
and ram.
I've run ConcurrentDOS-386 in 4mb as a multiuser box save for some
of the programs (not the dos) wanted large tracts of ram.
Minix can be run from floppy, or the full package fit in some 40mb
and on a 386 with 4mb it's pretty interesting. However it's a
research non-GUI OS so things like networking are not as pretty.
