The modules have been tested under Microsoft's Explorer 4.0 and Netscape Communicator 4.5 for Windows 95 and NT. Versions of the browsers prior to July 1998 are not supported. Older versions of Explorer may work while versions of Netscape's Communicator will likely not. The uncompressed applets are approximately 1 megabyte in size and should present no difficulty if being used on a local network or high-speed link. The module execution should be adequate on systems having at least 133 MHZ clock speeds and sufficient memory for running browsers, word processing applications, and spreadsheets (e.g., >= 48 megs). At the time of writing, the Explorer browser is the recommended platform.
