I'm using CUSeeMe version 83b3 on a PPC 6100 with System 7.5.3. You need
to use the Network Software Selector (Apple Extras folder) to choose
Classic Networking (using MacTCP) instead of Open Transport. I need to
hit up the docs again to see if there is any discussion of the best memory
configuration. It's running alright using RAM Doubler, but when I have
more than two CU windows open things get real slow. I have 16 MB installed
with RAM doubler.
