Good news from the #CZSpectrumPlus that I am trying to get back to life:

having replaced the proprietary #ZX8401 chip with a modern FPGA based replacement, the system now comes up again - wooohooo !! 🥳

I've also replaced the old keyboard membrane which had brittled to oblivion with a new one, however only a fraction of the keys are working. Maybe I need to replace the keyboard "big" ribbon cable connector as well (I already replaced the "small" one).

But things are going into the right dircetion ...

EDIT: I've replaced the "big" / "wide" keyboard connector with a new one and now all keys are working. More footage later, gotta go now to get cat food.
