Linus, Steve, thx for your option on this. I not sure if "museum style
equipment" really applies here, as the hardware seems to be sold in
2013/2014 and according to the reporter even got a update in 2016. But
whatever, yes, it's niche thing and what the hw manufacturer did there
was a bad idea.

Anyway, I'll stop tracking this then.

#regzbot invalid: to niche/risky/old, see Linus and Steve's messages for
