VIC-20 interlace text mode

The NTSC-M version of the VIC-20 has a little known capability of
producing a true interlaced output.  I created this little program
to demonstrate how it can be used.

This package contains the following files:

README
  this note
GNUmakefile
  Makefile for GNU Make.  You will also need Perl 5 and DASM to compile
  the program.
interlace.s
  Source code in DASM format

font.bin
  An interlaced font generated from a 16-line font
  from the Debian GNU/Linux 1.3.1 package kbd.
  The codes $00-$3F are mapped as expected; to save memory, there are
  only 128 codes, and reversed characters have codes $40-$7F.
interlace.prg
  The interlace demo program.  Load it into an unexpanded NTSC VIC-20
  and RUN.

The latter two files are generated by GNUmakefile.

Due to the small size of this package, the GNU General Public License
is not included.
