This is an emulator for the Apollo dn3000 and dn3500 that I wrote, based on the Musashi 68000 emulator. I call it the Otterlator. It's far from complete but you can run the prom debugger.
Also contains a MacOS executable, thanks to Landon Rodgers.

I'm no longer working on my emulator because Hans Ostermeyer has written one called ost.apollo.mess based on mame/mess that is complete enough to run Domain/OS. You can get it from the Apollo Archive.
