can we use an emulator and if so which

Wow, sorry for the late response, I hope you're still considering running! But, yes! I'm not a moderator, so you might want to double check with Retro and/or the rules listed, but for my run, I used a popular Apple II emulator (as cool as it would be to be able to get my hands on an actual Apple II.) Just be sure to check whether or not your settings/desires are for the quicker "enhanced" speed, or the "authentic" speed. Happy typing!
