From experience at our site with both troff and TeX, if you have an
LN03, you had better plan on buying two RAM cartridges.  With none,
you only have about 28K available, and I doubt if you could even load
two 10-point fonts.  With only one, you must plan on having to delete
fonts during the printing of a document, and my experience with this
is that there seems to be a bug in the LN03 that sometimes screws up
the fonts if you start deleting them.  By the way, my overall
impression of the LN03 is quite favorable.  The quality of the output
is extremely good, even after 9000 copies on the original OPC belt
cartridge.  For you programmers, here are some anomalies I've noted in
the unit that are either not clearly addressed in the manual, or are
wrong, at least as I understand it, so if your unit doesn't exhibit
it, I'd be glad to hear from you.

1) Setting DECOPM so that coords are relative to the physical page
instead of the edge of the printable page does not work.

2) If you create fonts, note that the LN03 truncates rather than
rounds the conversion from decipoints (Gutenbergs, depending on your
version of the manual) to pixels.

3) The first coord on a page is (1,1), not (0,0).
