                     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 is 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
available, 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, almost all characters in the set from ASCII
33 through ASCII 254 are available, using Alt key combinations for characters
above ASCII 127. Due to limitations in the Windows implementation of the ANSI
standard character set, a few characters are not available. This is not a
fault of the font, but a quirk in the way Windows uses some of the ANSI
characters. This limitation should not pose a problem for most applications.
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.
