Hi again.

When I have more info (re the early CPU's etc)  I'll come back here with it.

Agreed re "appliance" NAS devices, "shouldn’t be running arbitrary
code".  But see the recent news re most WD MyCloud devices!Hard coded
back door's etc, so "some malicious bar steward" could probably plant
such if they wished.

Do you know about the "Shodan" search engine?   That makes it all too
easy to find web facing appliances.  Cameras, drives, printers, PVR's,
light bulbs and other IoT "things"...  Enjoy!

Thanks for now.

    Dave B
