Yup, you can run Linux with Xwindows on a 4 MB system, and it works
even better with 8MB.

But, I get 133 MHz Pentium boxes with 32+ MB and sometimes 1GB+
hard drives out of the dumpster at work. I'm doing most of my EMC
development work on one of these.

There is a problem with the memory architecture on the 486 and below.
The virtual page size is different, which requires some tweaks in how
the shared memory is allocated between the RT and Linux sections of
EMC. But, yes, EMC will run in 4 MB with the character-cell GUI
keystick. It may run on Red Hat 5.2 with the XEMC GUI in Xwindows,
but you'd better not run anything else. With 8 MB, you can probably run
the TkEMC GUI in X, if you restrict yourself to only one extra window
for editing.

But, don't expect Mandrake 8.2 or the latest BDI CDROM to work well
on an 8 MB machine. And, it may not even install on a 486.
