PostScript Type 1 and TrueType Typeface

A Pixel-based, Fixed-pitch, PC-8 character set, Computer Screen Typeface.

Video Terminal Screen (VTS) resembles screen 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 fixed-pitch, 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 PC-8 character set used by IBM-PC
and compatible personal computers. (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, a Low Characters file (with the italic font file attribute) and a
Box Characters file (with the boldface font file attribute). The Low
Characters 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 Box Characters file contains the box characters
remapped down 128 character positions.

Typical of fixed-pitch fonts, Video Terminal Screen has a low aspect ratio,
producing a somewhat short and "squatty" appearance. 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 Low Characters file
contains these characters, shifted up 64 positions. For instance, the open
smily 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 Low Characters 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 Box Characters 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.

Other TECH/TYPE Typefaces Available from E A BEHL
Since its re-release in November 1992, VTS has become extremely popular in
the technical documentation industry for documenting DOS screens. We are
proud to announce the recent release of a white-on-black companion typeface
to VTS -- Reverse Video. Reverse Video has all 253 PC-8 characters and comes
in 3 files just as VTS does. With Reverse Video, you can now highlight text
in the DOS screen capture and print it as reverse video characters.

There has been some interest in a "bold" version of VTS -- but VTS is fairly
dark as it is. As an alternative, we have been developing Video Lite -- a
"light" variation of VTS, which will allow the distinction between normal and
high intensity characters in print.

Alphanumeric is another pixel-based fixed-pitch typeface that resembles the
5 by 8 pixel characters of liquid crystal displays (LCD's) and dot matrix
printers. Alphanumeric contains all 96 standard ASCII characters, many
international characters arranged in their PC-8 positions, Greek and math
symbols, and several graphic characters.

Dialtone is a key caps typeface for pushbutton telephones. A great typeface
for printing telephone dialing instructions with a graphic touch, Dialtone
contains the full 12 button dial keys, with number keys in both Metropolitan
(letters and numbers) and International (numbers only) styles, the star and
pound keys, and the A, B, C, and D keys for military and special purpose

Seven Segment (still under development) is a typeface containing numerals
and symbols made up of seven bars (or segments) arranged in a figure 8
pattern, common in digital alarm clocks and appliances. Numerals with a right
decimal point are in the shift-number positions. Seven Segment also includes
a limited set of alpha characters including the A, b, c, C, d, E, F, G, h, H,
J, L, n, o, P, r, u, U, y, and the Greek Mu (micro) symbol. Punctuation
includes the hyphen (dash), underscore, and equal sign.

Also in the planning stages are:

* A higher resolution equivalent to the VTS family,
offering DOS screen captures with greater readability.

* A sixteen-segment alpha and numeral typeface, along the
same line as Seven Segment but with more alpha characters.
