Schmoburger - The Mac II is unique in that respect, it needs good PRAM batteries to boot. I think the same applied to the Iix and IIfx as well. They can be jumped to start. Also the early Mac II boards use solid caps that don't need replacement. Not sure if tats or ceramics.
Ah well there ya go... the more you know.

And yeh I do recall that now about the caps... I remember seeing a Mac II board some time ago and being over the moon at he fact there was not a single electrolytic in sight, and from what I recall, there is only a single electrolytic axial cap on the SE logic board as well.

I think all the bad caps they decided not to use in the Mac II or SE must have ended up in every SE/30 ever made. lol
