Known issues:

  • Leaky Ni-Cd clock battery.

Remove the Ni-Cd battery as soon as possible and neutralize the leakage using white vinegar. Some more in-depth look may be needed to properly fix the motherboard. The battery can then be replaced using this https://github.com/wiretap-retro/Not-A-Varta.
