-
- Welcome to "The World's Simplest Computer."
-
-
- *******************
- ** What is it? **
- *******************
-
- "The World's Simplest Computer" is a 66-page book which
- illustrates the basic operation of digital electronic
- computers.
-
- It is not a program. Rather, it is a collection of
- computer art files, in the GIF format, which illustrate
- basic concepts of personal computers.
-
- The computer art was accomplished in the EGA 640x350
- 12-color format. However, it can be viewed by any
- computer which can display GIF files of this resolution
- or better. Sorry, CGA will not work well enough.
-
- The concepts covered in the book are . . .
-
- Bits, bytes, nibbles, and words and how they represent
- numbers, letters, and ideas.
-
- How bytes represent ASCII and pixels. How ASCII letters
- are converted to pixels.
-
- Addresses, the CPU, RAM, the bus, interrupts, chips,
- and memory maps. How a computer adds bytes.
-
- Computer hardware: Disk drives, the keyboard, the video
- display, circuit boards, dip switches, and other add ons.
-
- Bugs.

-
- Writing a program . . .
- Loading the language
- Typing the new program
- Translating the code
-
- Computer "intelligence"
-
- The world's simplest computer
-
- All concepts are illustrated.
-
- The concepts apply to all types of personal computers,
- not just IBM compatibles.

- ** Who is it for? **
- **********************
-
- This book is for four types of people:
-
- 1) Computer beginners.
-
- 2) Intermediate computer users who "just don't
- understand" what is going on inside a computer.
-
- 3) Experienced computer users who need to train the
- above two types.
-
- 4) People in computer stores who can use it as a
- slide show display.
-
-
- ********************
- ** Installation **
- ********************
-
- This book does not supply a program to view the files.
- You must supply your own.
-
- Many GIF viewers are on the market, and no single one is
- "the best." It depends on what computer you are using
- and on what type of video display you have. Many of these
- viewers are located on CompuServe in the GRAPHSUP forum in
- LIB 3 (Decoders & Encoders).
-
- That said, the book has been tested on VPIC (see the
- tutorial) for IBM compatibles. To find VPIC, search the
- filename VPIC*.* on the above-mentioned forum and library.
-
- For general help on graphics, enter GO CIS:PIC-1 on
- CompuServe.
-
- Once you have a viewer, place all of the files for this
- book in a unique directory. Start the viewer and specify
- the directory which contains the files for this book.
-
- Start with PAGE00 and continue in order to PAGE64. Go
- at any time to PAGENDX which contains the index to the
- book.
-

- ** Tutorial **
- ****************
-
- If you are reading this on your computer screen, you
- should first print the manual. Make sure all of files
- are in the default directory. Refer to a DOS manual
- to see what this means. To print the manual, enter
- PRINTMAN from the DOS prompt.
-
- It is assumed that you will be looking at the printed
- manual as you try out the book.
-
- This tutorial is for VPIC (see "Installation" on where
- to find VPIC). However, many other GIF viewers can
- also be used to display this book.
-
- The tutorial is a series of steps.
-
- 1) Start VPIC (you may need to set it up, first, for your
- particular type of video).
-
- 2) Press <F9> and then enter the directory which contains
- the files for this book.
-
- 3) The files should be displayed on the video screen.
- They will be from PAGE00 to PAGE64 plus PAGENDX.
-
- 4) Highlight PAGE00 and press <ENTER>. You will see the
- title page. When you are ready, press <ESC>.
-
- 5) Highlight PAGE01 and press <ENTER>. You will see
- Page 1. Press <ESC> when ready.
-
- 6) Select each page in order until you are finished.
-
- 7) To see the book as a slide show, use the space bar to
- highlight every page. Then press, <F2>. Each page
- will be displayed in order for a few seconds each.
- Press <ESC> to stop the slide show.
-
- 8) To exit the program, press <ESC>.

- Langin Software.
-
- The author, Chester Langin has written a paperback
- book, "An Easy Course in Using DOS," illustrated by
- Virginia Rohrbacher. You can order it from Grapevine
- Publications by calling 1-800-338-4331. They accept
- credit cards. It's $22.00 plus postage and handling.
-
- The author has a program, "DosEA -- For Absolute
- Beginners," which is a hypertext tutorial on using DOS.
- You can download it from CompuServe (DEA.ZIP in the
- IBMAPP LIB 11) or send $5.00 to Langin Software. The
- registration fee is $39.00. It gets you a copy of the
- book, too, plus another program, "DosEA -- Find that
- Command!" which helps you find DOS commands to do your
- computer chores.
-
- You may also like "Hangman for Students," the
- classic hangman game with word lists divided by
- grade level, from Grade 1 to Grade 5 -- also
- junior high and senior high. Kids like it.
- Make your own word lists. Get a sample copy for
- $5.00. For the registration fee of $19.00,
- you get a supplemental program which allows
- ASCII text file word lists to be changed to a
- format useable by "Hangman for Students."
- On CompuServe, it is in IBMNEW LIB 6.
-
- Another program by the same author is "Tear Down the
- Wall," which builds a brick wall on the computer screen.
- You break out a brick and see how much falls. The more
- that falls, the more points you get. Play against the
- computer. Listen to Pink Floyd while you play (not
- included). Work out your aggressions. $5.00 gets you
- a sample copy, or register it by sending $9.00 and
- get a hint sheet, too. On CompuServe in IBMNEW LIB 6.
-
- "Nine Men's Morris" is an ancient game of strategy you
- can play against the computer. It is like tic-tac-toe,
- but more complicated. It looks easy, but isn't. Sample
- copy: $5.00. Register for $9.00 and get a tip sheet.
- On CompuServe in IBMNEW LIB 6.
