You are correct, that Mac has a SuperDrive in it. Sorry to hear about the spring, it must have come out during shipping, but glad you got it fixed! A little trivia about that floppy drive--when I first got the 475 from surplus, someone had removed the floppy drive. I put a NOS drive in there eight years ago and it hasn't seen much use at all.

Glad to hear you're having fun with it! Can't wait to hear about the full 040 transplant!!!
