The upgraded ln03 driver has been contributed by Matt Thomas.  It will
be found in the sub-directory thomas.  It is set up to use
pk fonts.  Note the inverted name ln03dvi for this driver.
The function is still the same.  dvi-->ln03 output.

Some write-white fonts are provided in cmfonts/gf/gf300w.
There were set for a Ricoh 4080, and may not be quite right
for the ln03.  They will still be an improvement on write-black
fonts.  At some time in the future all fonts will be sent
out in PK format, but if you find only gf format in cmfonts/gf/gf300w
you will have to compile and run gftopk (from MFware).
You can make up other fonts using METAFONT.  Look at the
RicohFortyEighty mode_def in U_Wash.mf (utilityfonts/bases)
make a copy of this into your own mode_def file, and
reset the parameters as necessary.  There is a good deal 
of discussion and guidance in recent editions of TUGboat
(volumes 8 and 9, passim).  Remember to include the line
input white_setup
in your mode_def file, (see the comments in U_Wash.mf)

The amsfonts may not be entirely satisfactory,
but they are the product of old Metafont79 and are not subject to
the same adjustments as newer fonts.  Even a WRITE-WHITE base may
not be entirely satisfactory.  THe nicks come out very blunt on
some characters, and pixel editing may be necessary in the long
run.
