PowerMac 7500 and CU-SeeMe

There have been several posts requesting information as to how to get the
PowerMac 7500 working with CU-SeeMe and the 7500's built-in video-in.

This is a repeat of a post I made about a week ago; I guess I'll either keep
repeating it periodically until everyone sees it, or until it's picked up by
an FAQ somewhere.


To get CU-SeeMe to work on an OT (x500) machine, you've got to do the

1. Install OpenTransport COMPLETELY.

2. Remove from the Extensions folder the libraries named "Open Tpt Internet
Library" and "OpenTptInternetLib". These are the libraries that have the
code for mishandling dialup connections. Also remove the TCP/IP control

3. Make sure that you have MacPPP 2.1.1SD or later (I use 2.2.0a) and MacTCP
2.0.6 or later. If you don't, they're available in the usual places.

This will permit AppleTalk to operate properly, but will supress OT's handling
of PPP networking.

Once I did all this, my 7500 was very happy to work and use built-in video
(with 0.83b2). If you try this on a 9500 or 8500 and have good/bad results,
please let me know what they were.

If you have questions or problems, please e-mail me directly; I will post
any necessary modifications to this procedure to the list.
