@david Not at all, really. "The present" is a series of emulation environments that are started up and shut down in an instant and have no persistence between them. All my virtual floppy drives are write-disabled by the emulator unless I enable it temporarily for testing, but I'll only do that on a temporary duplicate of the .woz file because I don't want the program's own data written to the disk either.
@david I would trust any disk image from Asimov FTP. On 8-bit Apple II machines, there's no persistence of any kind after openapple-control-reset. (On a IIgs the answer is more complicated.) If you have a hard drive, any floppies you boot could potentially write to it, but it's really a very minimal risk. There are anti-virus programs from back in the day if you want.
