Opened up the second Kaypro 2 machine. Prior owner had a note on it: “no power - worked for a while”.
Yep. Dead. Then I happened to feel the back and realized the fuse holder was empty and open. So I swapped one over from the first machine.
Power flows now, but it makes a metallic tink tonk tink tonk sound with the rhythm of a clock ticking. No lights. Guessing something on the power board.
But this motherboard swapped into the first has me booting again.
