Apple Ii Emulator Mac Free10/14/2021
These personal computers allowed people to own and operate their own machines with relative ease. Virtual Apple is a site that features over 1,300 games from the Apple II and Apple IIgs days, including The Oregon Trail, Tetris, Kings Quest, the Ultima series, Lode Runner, and many more.Introduced in 1977, the Apple II was launched as part of a class of small, inexpensive computers made possible by microprocessor technology. F1 - Show help screen F2 - Cold reset Shift+F2 - Reload conf file and restart F3, F4 - Choose an image file name for floppy disk in Slot 6 drive.A typical Apple II computer came equipped with 48 or 64 KB of RAM, and a 1.0 CPU. Over the course of its approximate 16-year lifespan (it was discontinued in 1993), the Apple II platform hosted seven versions of Wozniak’s original computer design. Apple co-founder, Steve Wozniak’s, wizardry with circuit design allowed all these features to fit into a small desktop machine with a lightweight plastic case.The Apple II was a stunning breakout success for Apple. It also had seven internal expansion slots that worked with the world’s least expensive floppy disk system at that time, the Disk II.
Each line is entered into computer memory by hitting the Return key.These three fundamental BASIC commands will always come in handy. Each line has a number, and when a program is RUN, the computer executes each line in numerical order from least to greatest. Some Syntax TipsEvery BASIC program on the Apple II is composed of lines of code. Microsoft created Applesoft long before it became famous for Windows.For this article, we used Applesoft BASIC. BASIC emerged in 1964 on the Dartmouth College Time Sharing System. It quickly became a popular educational tool for computer science due to its ease of use.The Apple II shipped with two major versions of BASIC over the years: Wozniak’s Integer BASIC, and Applesoft. The Basics of BASICFrom the late 1970s through the early ’80s, most personal computers included a programming language known as BASIC, an acronym for Beginners’ All-purpose Symbolic Instruction Code. Basically, you’ll be running an entire Apple II system in a web browser (it works best in Google Chrome).When you first load the emulator (or boot an Apple II without a floppy disk system), you see a screen like the one shown below.You hear a beep, and then see a “]” prompt with a blinking cursor.At the prompt, type the following and press Enter (or Return) at the end of each line: 10 X=X+1If you make a mistake, just use the left arrow key on your keyboard to move the cursor backward and make corrections. Make sure you use a machine with Applesoft in ROM, such as the Apple II Plus or later, or an original Apple II with the proper language card.If you’re following along without a real Apple II, open a new browser window to the Apple ][js uses JavaScript to simulate the circuitry of a real Apple II in software. It’s a quick way to test if BASIC is working properly on any system.If you have a real Apple II, power it up. Your First ProgramFirst, we’re going to write a very simple program that counts upward forever. Simply re-type the offending line, double-checking for possible typos.Got it? Let’s get started. To start a new program (erasing the current program from memory), type NEW.If you make a mistake while typing in the program, the Apple II will return a “SYNTAX ERROR” upon running the program, and it will include a line number where the error occurred. So, on its first pass, the program adds one to zero, resulting in one. At the beginning of the program, “X” equals zero. Line 10: Here, we tell the program that a variable named “X” is equal to itself plus one. This will BREAK the program, interrupting its execution.So, how does this program work? Let’s break it down line by line: 10 X=X+1 You can also re-type the entire line.To stop the program, press Ctrl+C. The program then repeats this process forever, counting upward by one, and then printing the result in each loop.Now that you’ve had a taste of typing, listing, running, and breaking a program, let’s take a look at one that can do something with the input you give it.First, type NEW , and press Enter (Return). The value of variable “X” (now incremented by one) is fed back into line 10. Line 30: We use the GOTO command to send the program back to line 10 in a loop. Line 10: The program displayed a line of text on the screen. Type your name and press Enter (Return) to answer the question.Like some kind of arcane dark magic, the program knew your name and talked back to you! How did it work? Let’s take a look at each line: 10 PRINT "WHAT IS YOUR NAME?" The program will ask you for input with a question mark ( ? ). Find save data for steam on macIt goes into far more detail than we have here. The semicolon told the program to print N$ on the same line without inserting a line break.Now that you’ve had a taste of BASIC on the Apple II, you can tell all your friends you’ve programmed a vintage computer! In fact, you can even tell Steve Wozniak on Twitter.If you’d like to dive further into Applesoft BASIC, we recommend this wonderful online tutorial by Yuri Yakimenko. Line 30: The program displayed Hello, followed by a comma and space, and then printed the contents of the variable N$. The dollar sign is short for “string.” Every variable that includes letters must be a string-type variable. Line 20: The program asks for INPUT from you and stores the result in a variable called N$.
