The first non-Unix port of The X Window System server was, in fact, to an IBM
PC/AT running MS-DOS.  Looking at the development sources I see

        C> dir pcx.exe
        
         Volume in drive C is PCSOURCES
         Directory of  C:\SRC\X\MAIN
        
        PCX      EXE   241696   9-29-87   8:11a


The linker gives me the following sizes for this image:

	code		data		Udata
	207964		20402		19418


PCX loads all of its device drivers (ethernet, high-res smart color graphics
card, mouse/tablet/etc.) when it starts up, so there's no code hidden in DOS.
If you have an expanded memory card it will use that for font bitmaps,
otherwise it uses system memory.  There is also a TFTP server in there so that
you can transfer files to and from the PC while running X. 

The version that we ship with our Mechanical Computer Aided Engineering product
also has bound into it extension packages for doing sophisticated dynamic
feedback, geometric animation, and menu display.  Our User Interface Management
System uses roughly 2 dozen fonts and exercises even our high-end servers.

X.V10 runs just fine on small machines.
