3. COMPAQ PORTABLE
The Compaq Portable is known for two things. It is the first portable computer. By today’s standards it is nothing like a modern laptop. The 28 pound computer was the size of a small suitcase. Compaq is also the first computer to be 100% compatible with an IBM PC.

4. MARK I ENTER DATE/YEAR HERE (yyyy)
This relay-based computer is developed by Harvard University and IBM. Grace Hopper, then a Navy Lieutenant, becomes the first programmer of the Mark I.

5. APPLE II ENTER DATE/YEAR HERE (yyyy)
The Apple Computer Company is created and introduces the Apple II personal Computer.
It becomes the first commercially successful personal computer.

6. “The Father of Computers”
ANALYTICAL ENGINE
ENTER DATE/YEAR

7. THE MACINTOSH ENTER DATE/YEAR HERE (yyyy)
The "Mac" was the first commercially successful computer with the mouse/windows technology.
The mouse technology was already developed earlier by Xerox Corporation.

8. TABULATING MACHINE ENTER DATE/YEAR HERE (yyyy)
Herman Hollerith invents a tabulating machine that records statistics for the U.S. Bureau of census. Hollerith starts a tabulating company, which after various name changes eventually becomes International Business Machines (IBM).

9. The Atanasoff-Berry Computer
ABC
ENTER DATE/YEAR
HERE (yyyy)
The first electronic digital computer was invented by John Atanasoff and Clifford Berry at Iowa State University.
The Atanasoff-Berry Computer

10. NUMERICAL CALCULATING MACHINE
ENTER DATE/YEAR
HERE (yyyy)
Blaise Pascal builds the first numerical calculating machine. This device works similar to the old car odometers and could perform addition and subtraction.

11. MS-DOS ENTER DATE/YEAR HERE (yyyy)
Microsoft, an unknown little company run by Bill Gates, agrees to create the operating system for the IBM Personal Computer and becomes a company larger than IBM.

12. COLOSSUS ENTER DATE/YEAR HERE (yyyy)
This computer is developed in England in various stages and helps to decrypt the secret code message of German communication during Word War II.

13. WORDSTAR ENTER DATE/YEAR HERE (yyyy)
MicroPro releases WordStar, which becomes the most popular word processing software program.

14. INTEGRATED CIRCUIT ENTER DATE/YEAR HERE (yyyy)
Jack Kilby, of Texas Instruments, at Richardson, Texas invents the planar transistor, which allows creation of integrated circuits and later micro chips. This invention is a turning point between the monstrously huge and expensive computers of the past, and the much smaller and cheaper modern computers of today.

15. NAPIER'S "BONES" ENTER DATE/YEAR HERE (yyyy)
John Napier used some bones marked with special scales to simplify arithmetic by using addition for multiplication.

16. VIDEO GAMES ENTER DATE/YEAR HERE (yyyy)
The first video game was called Tennis for Two.
It was created by William Higinbotham and played on a Brookhaven National Laboratory oscilloscope.
Since this game did not use an
actual computer monitor, some
give credit for the first video game
to SpaceWar! written by
Stephen Russell at MIT in 1962.

17. THE ABACUS ENTER DATE/YEAR HERE (yyyy)
The Abacus was originally invented in the Middle Eastern area. This rather amazing computing device
is still very much used in many Asian countries today.

18. ALTAIR ENTER DATE/YEAR HERE (yyyy)
Altair becomes the first personal computer. It is created by Ed Roberts and Bill Yates. The computer costs $ and has storage for 256 bytes.

19. UNIVAC I ENTER DATE/YEAR HERE (yyyy)
The UNIVAC I (UNIVersal Automatic Computer) was the world’s first commercially available computer.
The computer became famous when it correctly predicted the results of the 1952 presidential election.

20. JACQUARD'S LOOM ENTER DATE/YEAR HERE (yyyy)
Joseph Jacquard invents flexible cards that are punched with information in such a manner that it is possible to program how cloth will be weaved. It was one of the first examples of programming.

21. THE SLIDE RULE ENTER DATE/YEAR HERE (yyyy)
William Oughtred created the slide rule. This device allows sophisticated mathematical calculations, which was widely in use until around 1970.

22. IBM PC ENTER DATE/YEAR HERE (yyyy)
IBM's entry into the personal computer market gives the personal computer a serious image as a true business computer and not some sophisticated electronic game playing machine.

23. ENIAC ENTER DATE/YEAR HERE (yyyy)
The ENIAC (Electronic Numerical Integrator and Computer) is the first functionally useful fully-electronic computer.
The computer is two stories tall, weighs 80 tons, contains 19,000 vacuum tubes, and is programmed by walking inside the computer.
The cost: $10,000,000

24. “The Mother of Programming”
ENTER DATE/YEAR
HERE (yyyy)
Countess Ada Lovelace was Charles Babbage’s assistant. She designs programs that work for Babbage's analytical machine. Some concepts
in today’s modern languages are based her ideas.
Today a programming language is named after Ada.

25. VISICALC ENTER DATE/YEAR HERE (yyyy)
Dan Bricklin created VisiCalc, a spreadsheet program, which becomes the first wide spread software to be sold.

26. MARK II ENTER DATE/YEAR HERE (yyyy)
A technician found and removed moth from one of its relays. This was the first computer bug. The actual moth is currently on display at the San Diego Computer Museum.
