I just read the specs and there is an SD slot.

First was a Novation CAT 110/300 baud with acoustic coupler. Later I got a Practical Peripherals 1200, then a Zoom Telephonics 2400/9600. Then I bought a US Robotics Courier HST, it cost a ridiculous amount at the time. A few years later was working and I mailed it and an actual check to USR and they swapped it for a Courier vEverything (with the 20Mhz DSP). I still have that modem and a newer vEverything I salvaged.
