There are a number of companies making muliPort cards for the MacII/ Nubus including: Creative Solutions, Taniwha, Tara Systems, Applied Engineering, Xecom, DigiBoard, and Apple. I think that's all. > o Are they any good? I have used most of the above, and other than misc. bugs that have been correctly pretty promptly, they all seem to work just fine. > o How does comm software interface with the board? In the past, comm software had to be 'patched' to work directly with these cards either via an INIT, or a binary/resource related patch to let the program know that it existed. Also there was 'shadowing' which simply remapped output to the modem port to a port on the card instead. > o Do they work with Apples Communications ToolBox? All of the cards currently support the CTB, and this is the recommended solution to using the cards as it is now system support for such things. > o Are you required to install special inits or drivers other than > CTB type drivers? Each card comes with an INIT which simply loads the drivers into the device table and then registers them with the CTB. If you do not have the CTB, then there is more stuff for doing shadowing, etc. Leonard Rosenthol Software Ventures Disclaimer: I have tested and continue to use many of the above cards in my machines. I can say whatever I want about them, and let them do as they may ;-)
