80 year old still uses Macintosh Plus and ImageWriter II

The worst part were those two damn screws underneath the handle that required like an 18" shaft. And yeah, needing the jaws of life to crack the case open was kind of a pain too.

After that it wasn’t too terrible to work on.

Nah, other than needing a long shaft it needed a slightly hard to find but by no means exotic T15 bit IIRC. Cracking open the case without damaging was a pain because you needed a spreader of some kind. Of course Apple made a specialized tool for this but you could rig your own with some minor ingenuity. A woodworking clamp can do the job just fine.
