     Just as I thought, I got a few nibbles.  What I forgot was that a friend
of mine has already uploaded the stuff to wuarchive.wusel.edu.  Here's the
message I posted last time we went around...

     Well, I finally did it.  Thanks to Anthon Pang, my FTP contact,
all of my line printer art is available for download.  In Anthon's
own words:

>I've uploaded those files to: wuarchive.wustl.edu (128.252.135.4)
>and placed them in the /pub/lpr_art.incoming directory.

     Here's a list of the files:

File                Bytes     Remarks

pinups.Z            38420     Assorted calendar girls


     Each file (when uncompressed) is an ASCII text file.  Records
are variable length to a maximum of 133 bytes, followed by a Unix/C
newline character (ASCII LF, hex 0A).  The first byte of each record
is a standard FORTRAN carriage control character, which can be one
of the following:

        blank - single space before printing
        0     - double space before printing
        -     - triple space before printing
        +     - suppress spacing (overprints the previous line)
        1     - skip to a new page before printing

The remainder of the record is the line image itself.

     The photo* files (except for photo.cat) contain a single
picture each, while the others contain several pictures.  Each
picture is preceded by a header record which has the following
format:

        1#*$FILE <filename>

The file name begins in position 10 and may contain embedded blanks.
If the file is to be printed at 8 lines per inch, position 133 of
the header record will contain an '8'.  Otherwise, the file is meant
to be printed at 6 lines per inch; position 133 will likely be
blank, and indeed the header record will be truncated to the end
of the file name in this case.  Most of the photo* files are to be
printed at 8 lines per inch to minimize white space between lines.

     Except for the photo* and art* files, most of the pictures are
simple (non-overprinted) images, which compressed by between 90 and
95 percent.  The photo* files were digitized at Princeton University
in 1973 by Samuel P. Harbison.  To get the desired shading, each
line is overprinted five or six times.  These ones are good.  Due
to their greater complexity, they compressed by only (!) 80 to 85
percent.  Be sure you have lots of disk space before you uncompress
any of these files - photo.moon is nearly a megabyte.  Most of the
photo* files print in several pieces which you then tape together
to get a large picture.

     If you have any questions (or printer art you think I'd like)
drop me a note.  If you don't have FTP access, send me tapes or
disks and I'll make copies for you.  I can do the following formats:

        9-track 1600 bpi EBCDIC, standard labels (fixed 133-byte
                records, block size normally 3990 but changeable
                on request).  A 600-foot reel should be big enough.
        9-track 1600 bpi ASCII unlabeled (uncompressed versions
                of the .Z files, strung together in a single
                7-megabyte Unix file)
        DC-6150 (150-megabyte) cartridge, same format as above
        5 1/4-inch 360K MS-DOS diskette (requires 4)
        5 1/4-inch 1.2-megabyte MS-DOS diskette (one should do it)
        3 1/2-inch 720K MS-DOS diskette (2)
        3 1/2-inch 1.44-megabyte MS-DOS diskette (I'd prefer
                720K though, I can't do 1.44-meg format directly)
        3 1/2-inch 880K Amiga diskette (2)
        3 1/2-inch 800K Mac diskette (2)

Enjoy...
