The files SE1420*.* are the ascii and typeset versions of the 1919
U.S. Navy Type SE 1420 Medium Wave Radio Receiver manual.

Note.... as of this time, page 9 is missing.  Someday, when someone can
locate a replacement page 9, it will be added back into the manual.

The ascii manual is SE1420.MAN.  It will print on any printer.

The typeset manual is SE1420A.PS, SE1420B.PS, SE1420C.PS, SE1420D.PS and
SE1420E.PS.  It will print on any postscript printer PROVIDED you have
sufficient printer memory to handle the images.

The SE1420.NRO file is the nroff source of the ascii manual.

The SE1420*.TRO files are the troff sources of the typeset manual,
and the graphics images scans are the *.eps files for the figures.

The manuals are gzipped on dos to make filename.psz files.  Uncompress
them with the gzip.exe utility on dos OR rename them to *.ps.gz on unix
and use the unix version of gzip.
