Two good things:

First, the drive was erased really well, it wouldn't be worth the effort.

Secondly, the device can still be used excellently for demonstration purposes and to explain things.

I got an old router, #pcengines #ALIX 2D2/2D18 with wifi, from a company liquidation (bankrupt). The device was in operation in the field at the tank control and mixing unit. Let's see what artifacts can still be found. #otsecurity #hardware #icsSecuruity
