My dad has an old Mac Performa 6215cd with an external 56K modem.
I'm hoping to be able to use that modem with this new Linux box,

Some of the old macs had a serial port form factor like you describe. The plug looked like a PS/2 keyboard/mouse plug, though the pin arrangement was different; electrically it was an RS-232c port but missing one of the signals. (I don't recall which signal, but I think it's only important if you want to receive calls.)

You could look for an adaptor at Fry's or go online, but that hardware has been considered obsolete by the marketplace ever since the first iMacs came out. I think you're more likely to find something to use a standard modem with the mac than to use a mac modem on a standard PC.

Short of buying a new modem or a new/refurbished mac that runs unix and has a builtin modem and a warranty and runs all of your dad's old software and everything just works, your best bet might be to open the modem case and see if you can replace the cable with a PC-style cable. Or you could cut the end off the cable and install a new plug, if you could figure out the pinout. You have a soldering iron, right?
