Many years ago I acquired a 540c and 520c in a single eBay auction. Both operate perfectly (the 520c screen was kind of janky), but the 540c's case was slightly beat up/required tape to keep parts on it. So recently, I cannibalized the 520c's case and moved over the necessary parts to the 540c. I am now left with a perfectly functional 520c motherboard, processor, floppy drive, etc.
Once the processor is removed, is the 520 motherboard identical to a 540 motherboard? I am wondering if it makes sense to keep the 520 motherboard as a "backup" should anything happen to the 540 motherboard or if I should try to trade the 520 board.
Thanks!

I would keep it for the 540.
Yes, the Powerbook 5x0 series all share the same motherboard - only difference is the CPU speed. For all vintage machines you keep, I think it's a great idea to store away a spare motherboard just in case. Same goes with RAM, LCD, fragile case parts.
