If you want that nostalgia to feel or you're just curious how did one of the first Apple operating system looked like, we recommend giving this emulator a run, it's easy to use, lightweight and can be fun for a couple of hours. The developers also acknowledged there aren't that many applications and documentation for Apple II lying around so they included a resource section which you can access. The emulator's interface is rather simple to use, booting the operating system looking identical with the old Apple II. AppleWin can run programs from disk images, which come in the form of floppy disk images. The emulator doesn't require an installation, it can be unpacked and run directly from your hard drive or USB storage device if you prefer on keeping it on a flash drive for example. While the OS itself was forgotten, some users simply like to install it for nostalgia purposes or just for accessing data they had on their old computers.ĪppleWin is an emulator for Apple II that can be copied and run on any Windows installation. The program will JuMP to address $FBDD when run.AppleWin: Get a first-hand impression on how the first 8-bit microcomputer from Apple works using this simple and straightforward applicationĪpple II is Apple's first successful 8-bit operating system, dating back to 1977. That's a one line machine language program from the three bytes you stored in memory. The important part are the three bytes at the top that disassemble to "JMP $FBDD" displayed beside the three bytes. The first line of the listing should be " 0300- 4C DD FB JMP $FBDD" To see a listing of the program, type the following: Those three bytes " 4C DD FB" in memory are a machine language program! You should see " 0300- 4C DD FB" displayed. To see the range of three bytes, type the following: You've now got 3 bytes in total that you've stored in memory. To see the byte you just stored into memory, type the following: When using the monitor don't type the dollar sign in front of the numbers because the monitor expects all numbers to be in hexadecimal without a dollar sign in front. When writing an explanation, I am putting a dollar sign $ in front of hexadecimal numbers. Overall, the game looks much better this way. If you don't want that, you can change the model to Apple II+, which didn't have the 80-column card. Wizardry recognizes it and adapts the menus to it automatically (by adding spaces all over). All numbers in the monitor are in hexadecimal. AppleWin's default config emulates the Enhanced Apple IIe, which has the 80-column card built-in. This stores the byte $4C into memory at address $300. You should now be in the monitor with the * prompt. If you are not already in the Apple II monitor, then type the following statement from BASIC: If you are in Integer BASIC you will see a > prompt. If you are in Applesoft BASIC you will see a ] prompt. If you are in the Apple II monitor, you should see a * prompt. I haven't actually tried any of the code on my actual Apple IIe enhanced just yet. I've tried unchecking the CP/M card option, and changed the simulation from enhanced IIe to just IIe. All I can think of is that it's something in the configuration for Applewin. Here is the source code for the second video I'm trying to use: When I tried a different video which use OBJ $300 as the second line in the source code, I get the error "Bad "OBJ" in line 2". For example, I type in the exact source code as seen on the YouTube video, I use the same Merlin commands as well, the program completes the assembler process wihtout errors and it matches the exacts output in the video, but I am unable to get Applewin to save the object file after I save the source file. I'm having issues with objects and object files. I'm trying to re-learn 6502 assembly by using some YouTube videos with Applewin and the Merlin assembler.
