In AppleWin, if I set up the emulator to Apple II original, I can boot to the monitor and then switch to Integer BASIC with CTRL/B+ENTER, but I can't find a reliable way to boot to DOS.
If I set up the virtual disk drive (1) with a DOS boot disk, and reboot the emulator, it still boots to the monitor, as it does if I double click the .do disk image.
The only way I found to boot to Apple II original mode with the DOS available is to switch to another machine (eg. Apple II+), reboot the emulator, then switch back to Apple II original and reboot once again.
This way I get to the DOS prompt (albeit with a FILE NOT FOUND error) and I can access Integer BASIC programs on the virtual disk with LOAD.
Am I doing something wrong or is this a glitch with AppleWin? (I found no evident settings to populate the virtual expansion slots).
