I think GNU needs at least a megabyte or so on a VAX to be happy, probably
more if you want to edit anything with it.  Under MS/PC-DOS, the memory
limitations would make it impossible; but on any 808x/80286 you'd run 
into lots of trouble in getting around those stupid memory segments.  If
its a megabyte of executable on a VAX, you might end up with 1.25-1.5
megs of code on a PC just getting around the segmentation (i.e. somehow
you've got to handle pointers as 32 bit memory addresses).  This would
also cause the code to grind to a halt speedwise -- I recall reading
that the Lattice "large code model" calls subroutines to handle almost
any kind of pointer interaction.  You CAN get MicroEmacs in various
flavors here on the net; the last version I saw posted was an IBM PC
specific version.  I don't know if anyone's postulated the minimum
system for practical GNU, but I'd bet its something more powerful than
a PC.
