Since this is commercial and has been rolling along for a few years now I infer that there are still customers out there, who in some incredible fashion, cannot get off of OS/2. And, based on what features ArcaOS concentrates on, they must be stuck on 32bit with pretty old, yet hard to emulate well, services: SCSI for example.

I envisage a 1996-era Gateway PC in the bowels of Madison Square Garden controlling the light show for Aerosmith or something. But then my mind goes, really? There's no path to Windows, or Linux, after 30 years?

I can understand people staying on z/OS, or even AS/400, but OS/2?
