Just an FYI: I am using a bondi blue iMac- rev.B. When I tried both the Apple Internal 56k and Apple Internal v.34 modem... my computer couldn't find the modem. I then submitted a bug report after rebooting in classic. Realized I didn't try any other modems... so I booted back into X, and tried the Hayes compatible (v.34) connected. Tried the Global Village 56k and connected!
