MacCIM 2.3 (CompuServe Information Manager) is compatible with Power Macintosh and GeoPort, but the automated sign up program is not compatible.
New members (who don't have ID numbers and passwords) trying to sign up can call CompuServe Customer Service at 800-848-8990. They will walk customers through setting up MacCIM.
This customer service number is also on the back of the CompuServe documentation and within the MacCIM program.
