I imagine it's quite difficult. Maybe not "functional Twiggy drive"
difficult, but probably "unmolested 128k Macintosh" difficult.
It of course depends on who you know, and who you ask. Undoubtedly
there's a guy out there with a stack of them in a shed somewhere, but
getting hold of him is a different matter entirely.

I assume the thing has a battery somewhere - I just hope it isn't
Ni-Cad!
At that age it might well be. So what? I think they are still
available. Or you can replace it by a non-rechargeable battery. That's
what I did with the ToD clock battery in my Pro; a lithium coin cell with a
series diode to prevent "charging" is not an ideal solution but adequate,
and it would be better if I used a Schottky diode rather than a plain Si
rectifier diode I happened to have lying around.

Battery leakage was the issue - having dealt with a great many logic
boards damaged or destroyed by leaking Ni-Cad batteries.
I've since seen a photo of the inside of the NeXT and it looks like they
used a plug in Lithium battery, so that risk is no longer of much
concern to me.
