Great tip from Nelis Willers:
230 V safety on the work bench.Put your power supply in an old tablet container. The high voltage is safely encapsulated and will not accidentally touch something. Of course don’t do this for a kW supply, only where low heat is generated, otherwise you might set a fire!

This appeared a few days back: [WayBack] http://bitsavers.trailing-edge.com/pdf/apple/ssafe/Apple_SSAFE_Project.pdf
It’s about “Software and Security from Apple Friends and Enemies” an early exchange of ideas and possibilities for DRM in the Apple ][ and Apple III era.
I got it via my bitsavers.org RSS subscription, but it has been over the net in quite a few other places as well:
I think the most important quote is from the one on reddit, submitted 20170223 by vadermeer for which I added some WayBack/Archive.is links:
[WayBack] Found Internal Apple Memos about copy protection for Apple II, SARA, LISA(self.VintageApple)
The reddit thread is very nice reading as it explains how close we are now to this Level 1:
Level 1. Totally secure. Absolutely no method of stealing the software. 100% effective. Note that the ideal, level 1, is achievable only through disallowing any access of any kind to the software and the computer. Not very practical in our circumstances.
and this one from boingboing:
It’s so neatly packaged and well-documented it could be a Harvard Business Review case-study.
