Under Mac 7.1 it gets definitively recognized as Mac II. I definitively have a SWIM, since one of my two floppies reads HD disks, I checked Penguin says my gestalt is 6, Mac II A clue for the MacII is the 68020 CPU + FPU + MMU, AFAIK the only apple machine with these specs. I tried to boot a current 2.6.18 kernel just for fun, it goes past the letter screen and dumps stack after recognizing the TOBY frame buffer card and attempting to init it. Riccardo PS: I didn't use this mac since many months, it first stasrted up, but then refusedfurther boots with the sad mac sound and no video output. REmoving components trying to isolate the problem didn't help. When I put al back together with no luck, a last attempt made it boot. Any ideas? I see no visible damage on the motherboard, the batteries still have some juice left...
