As far as i remember, their hard drives were prone to failure (the motor will not spin off).

As someone who lives in a place where shipping one would be more expensive than the machine itself, are there any good emulation options?

Even if we need to deal with the lack of Domain/OS specific keys.

Yes, MAME emulates the DN3500 era hardware mostly acceptably. Setup instructions are available online but reference MESS since they were written before MESS was merged back into MAME.

I need to find those. And get a more powerful workstation.

If you get or do a full build of MAME they’re just in it. Try the `dn3500` system. ROMs will be wherever you get MAME ROMs and Domain/OS install tape images are on Bitsavers.
