@Laberpferd @mdhughes yeah, #QNX was used quite a lot in the early 90s as an #OS for appliances like the #iOpener...

Sadly it's #CCSS so whilst it does work for some I can't really built upon it unless I'd also want to make a #commercial #ClosedSource solution.

Not to mention #Linux is really trivial to port, cross-compile and comes with all the drivers I could ever need...

Yeah, that's some major fuckup in terms of #DRM:

#iOpener from #Netpliance was trivial to #mod into being a #Windows #PC...

Seriously, had these things been sold in #Germany and had I been 15 years older at the time, I would've convinced my father to by a dozen, let me mod them and resell them with a huge profit margin...
