I only need about 250K for a compressed kernel. Remaining 750K is for
a filesystem with compression (something i've developed around ROMFS)

Little programs, thats why I dont want to lose memory with ramdisk

ROMFS is a filesystem, not a block driver. It needs a block driver to
access ROM memory. And it has been called ROMFS because it's
readonly.

I prefer kernel on RAM, files on ROM

It also has a PC/104, 8bits BUS (compatible with ISA)
Note that paralelle is useful for a zip drive (even if it doesnt
support EPP)
dims are 12.7 cm * 9.4 cm
I think about using it for a robot, or something like that.
Could also be used as a router and firewall on a slow link.
Also for the fun of making Linux run on every computer in the world.
Linux must run everywhere a Micro$oft OS runs
