It was thus said that the Great Shawn T. Rutledge once
stated:
Yeah if I was going to try to make do with 4 megs I'd try to cook up a
customized distro using some older code. TinyX can run in 4 megs in theory
but the web page warns that you may not be able to run more than 1 app
at a time. :-) But running all apps from a remote server should help.
I think with 8 megs you could run just about anything you want remotely.
TomsRTBT has some really small utils too. Whole collections of utilities
are implemented as symlinks to a single executable, and the executable
looks at the command line to figure out which utility to run. There's a
similar package listed at freshmeat called "busybox" but I'm not sure if
that's what Toms uses. libc5 and a.out are also a good thing in a small
amount of memory especially if there aren't going to be a lot of processes
running at once (elf has overhead but saves memory if the same lib is
linked to multiple executables that are running at once). Somewhere
I have a slackware so old that it uses a 1.0 series kernel. It has light
memory requirements but nothing I could do would make it work in 2 megs
of RAM like I wanted to do with those 386's. The kernel would load but
there wasn't enough memory left to run init. :-)
An idea I bounced off one of the mailing lists was what if code could run
in-place directly off the "hard drive" (FLASH in my case) without having to
be loaded in memory first. But AFAIK noone has done this yet. My guess
is it would involve modifying the loader (in the kernel or in libc? Not
sure which) to instead do an mmap and return a pointer to that space.
But I gave up thinking about it and resigned myself to make do with DOS
and build a custom lightweight GUI framework. At least the metawidgets
concept is very portable, moreso than X even.

Be warned, while you can run Linux with 4M of RAM, installing Linux with
4M of RAM isn't easy. It took me the better part of a day to install Linux
on a Toshiba T1900C with 4M RAM and 120M harddrive (a half-baked manual
installtion of RedHat using Tom's Root/Doot disk and an existing RedHat
system) and a 3Com modem/ethernet PCMCIA card (and it's currently hooked
into the network at home).
The RedHat install requires 16M of RAM. The oldest Slackware distribution
I found (3.3) required 8M to do a floppy based install. Don't even attempt
to run X if you have less than 16M and even then, you going to have to use
an older window manager like twm or fvwm/fvwm2.
If anyone is interested I can go into more details about how I installed
Linux on the Toshiba (in total spent about three, four days trying to get
*anything* installed on the box).
FWIW my first Linux box was a 386 with 5 megs. So slackware really did used
to run in that just fine. I was using a 1.2 series kernel then.
Sounds like great fun. Personally I'm hooked
on touchscreens though.
Haven't got it working yet because cheap deals on touchscreens always seem
to come with caveats...
At the Miami Ham fest earlier this month, I came across this one table
where the guy was selling a prototype Linux PDA. IBM made these touch
screen computers (basically they look like a thich LCD screen and are jet
black) with a stylus. He slapped a 1G harddrive and installed Debian Linux
on the thing. To Linux it looks like a standard PC, but it was a (I think)
33 MHz 486 with 8 or 16M RAM and a 1G drive. He wanted $250 for it.
Tempting, but decided for the Sun 3/80 at another booth.
