I need some advice. I have Telefinder Server 5.1 running on a Mac Quad 610. I have ordered the ISDN line to be installed this week. I have a dial-up modem connection to my ISP. In addition, I would like to create a dial-up ISDN connection for my customers. First of all, what hardware is recommended? My Quad 610 is half-height and I would have to be an adapter for the NuBus Planet Card. I am sure that would help the serial port problems, but is there a better solution? Farallon Netopia, Motorola BitSurfer, Ascend Pipe 50? Current Configuration 250Hard Drive, 40MB Ram, 7.5.1 Advice greatly appreciated!!!
