You make a PPP serial connection with Miami just like you would dial up an internet provider over a modem but no phone number is needed and no user name or password.
I have the device, I just need to find it and I will post the information.
The mounting method is normal. I don't know about the noise you stated. It should have a bolt that holds it on the back of the unit. The instructions that I had were only a few pages of badly photo copied information I got from Transnational in Anaheim, CA. I don't think I have it any more since I had given all the information and magazines I had to you last time you came down.
I would love to come down to your house for an Amiga meeting.
