My 640 works with the C key, so i guess apple introduced it around those models

I remembered that the 640 would boot from "C', but I'm still sure that the 637 would because it has the "CD" following it, and the "C" key was something that they brought in with CD models. Quadra's, though, were a pain with the four-finger hand cramp afterwards. But the four-finger hand cramp would overide any command from "C" and you can use it in conjunction with a number that coresponds with the SCSI bus and you can boot from that number.
