- A Pixel-based, Fixed-pitch, PC-8 character set, Computer Screen Typeface.
-
-
- Introduction
- ------------
- 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 the 222
- characters from ASCII 32 through 254. PostScript Type 1 and TrueType font
- files do not allow convenient access to the characters below ASCII 32.
-
- To allow access to the full character set, 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. These two files are provided only in the commercial version of VTS.
-
- 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.
-
- For tips on capturing DOS screens using the Windows Clipboard and importing
- them into Windows applications, see the accompanying File VTSNOTES.TXT.

- 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 two companion typefaces -- Reverse Video, a white-on-black
- variation for highlighted text; and Video Lite, a lighter variation for
- distinguishing normal from high-intensity text. Both Reverse Video and Video
- Lite contain all 253 PC-8 characters and come in 3 files just as VTS does.
-
- 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
- dials.
-
- Seven Segment 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 colon (of
- course), 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.
