I sent a reply to this, and got a DELAY bounce from google.
Assuming it will make it, I'll add here that this conversion
resulted in an image that is almost 'real'. Quite good. Almost
there:

jpegtopnm monica13.jpg | ppmdither -red 4 -green 4 -blue 4 | \
 ppmtobmp >/tmp/2.bmp

jpegtopnm: WRITING PPM FILE
ppmtobmp: analyzing colors...
ppmtobmp: 30 colors found
ppmtobmp: Writing 8 bits per pixel with a color palette

------
The only difference between that and David's original script is
the 4 instead of 2 values for the colors. 3 and 5 didn't work.
------
This is with the original 2:

jpegtopnm: WRITING PPM FILE
ppmtobmp: analyzing colors...
ppmtobmp: 8 colors found
ppmtobmp: Writing 4 bits per pixel with a color palette

-----
That 8 bits per pixel with 4 is the main difference, I think.
------

/tmp<#>xli 2.bmp 
2.bmp is a 400x533 8 bit deep, Windows BMP image
  Default gamma for IRGB image is  2.20
  Compressing colormap...30 unique colors
  Building XImage...done
