USRobotics Sportster Winmodem 33.6
The USRobotics Sportster Winmodem 33.6 is an internal soft-modem. Originally a 33.6 modem, as the modulation is powered via software, it can be upgraded to V.90 (56k).
The USRobotics web site claims this device only works under Windows 3.11 and 95, and maybe 98/ME.
The device does not have any clear markings, and has only a barcode with (in the device photo) "21TS67123339 04168001 R:2". The key here is the model code "04168001" - 04 is the country code for Asia/Australia, and 1680 is the product number. 01 refers to device variant "A".
- USRobotics still maintain a support page for this model, with manuals and driver downloads.
