Don't just plug it in! The power supply and/or VRM can fail in ways that deliver bad voltages to components. You might want to watch some of Lee's[1] videos first on how to bring up a ZX81 safely, or ask in his discord community for more help.

That is why my Timex 2068 has never left the box since around 1990.

Better admire for what it was and use an emulator instead.

Thanks for the tip! If/when I do I'll try to use a bench power supply so I can put a current limit on it.
