                     PostScript Type 1 and TrueType Typeface
 
             A monospaced, pixel-based, IBM-PC character set typeface.
 
 
General Description
-------------------
Video Terminal Screen (VTS) resembles characters of a data terminal or text
on an EGA/VGA monitor of a personal computer. Video Terminal Screen was
designed for use as a text font for technical documents such as software
programming manuals. The character set is monospaced, so that text captured
from an actual data session can be imported directly into a document with
minimal touch up.
 
The Video Terminal Screen typeface family consists of three font files
which make available all 253 characters of the IBM-PC character set (there
are no characters associated with ASCII 00, 32, or 255). The base (or
roman) font file contains all 253 characters, although standard encoding of
PostScript Type 1 and TrueType font files do not allow convenient access to
all characters.
 
To make access to the full character set more convenient, two other files
are included, which are identified as the italic and boldface members of
the family. The italic file contains the lower 31 characters remapped
upward by 64 character positions and the Greek and math characters remapped
down by 128 character positions. The boldface file contains the box
characters remapped down 128 character positions.
 
 
Background Information
----------------------
Typical of monospaced fonts, Video Terminal Screen is somewhat short and
"squatty." The character set is based on the "standard" 8x16 pixel
character set of EGA/VGA card character generators. For the sake of
simplicity and memory consumption, each character is an outline of the
EGA/VGA pixel pattern. Each pixel is a simple square. Character spacing is
provided primarily by virtue of the characters using only the first seven
columns of pixels, ensuring that adjacent text characters are separated by
at least one pixel width. In this way, when box and graphic characters
(which use all eight pixel columns) appear adjacent to each other, they
meet to form continuous lines.
 
 
Using the VTS Family
--------------------
The Video Terminal Screen typeface family is designed to conveniently
provide full access to the entire IBM-PC character set. Using only the base
font file in Microsoft Windows 3.1 or later, all characters in the set from
ASCII 33 through ASCII 254 are available, using Alt key combinations for
characters above ASCII 127. However, if the more obscure characters are
needed out of the set, either or both of the additional font files may be
necessary.
 
The 31 symbol characters from ASCII 01 to 31 in the IBM-PC correspond to the
ASCII characters Control-A through Control-_. The italic font file contains
these characters, shifted up 64 positions. For instance, the open smiley
face character, which corresponds to Control-A in the IBM-PC, may be
printed by typing an upper case A in Video Terminal Screen, then switching
the character to italic. The italic font file also contains the Greek/math
symbols from ASCII 224 through 254, shifted down 128 positions, so that
typing a grave accent (the key with the tilde) in italic produces the Greek
alpha symbol.
 
For convenience, the 48 box and geometric characters from ASCII 176 through
223, which appear in their normal positions in the base font file, also are
contained in the boldface font file shifted down by 128 positions. This
allows typing the characters from 0 (zero) to the underscore character,
then switching to boldface, to produce the box characters without using Alt
key combinations. This may be useful when Alt key combinations are not
allowed, or in non-Windows applications.
