AppleWin
As of writing this article, AppleWin is currently at version 1.30.20.0 and that (or the latest "stable" release) can be found at the official GitHub page. It's a fantastic Apple II emulator for Windows but as I've mentioned in a YouTube video, it's important to mention that the default MASTER.DSK image will boot with an error when using AppleWin's "Apple ][ (Original)" configuration.
The reason for this error had to do with the BASIC programming language. The original Apple II was released with Integer BASIC in ROM and later Apple II machines had AppleSoft BASIC in ROM. To fix this issue, I used assembly language for the startup program instead of using BASIC.
The modified MASTER disk can be acquired here. I used the DOS Order format and file extension so that it doesn't override the original MASTER disk.
