Practical Peripherals 08-02762 56K V.90 16-Bit ISA Internal Modem 5660US

The Practical Peripherals 08-02762 is a 16-bit ISA internal dial-up modem supporting speeds up to 56 Kbps via the V.90 standard. It installs directly into an ISA expansion slot on a desktop PC motherboard and connects to a standard phone line through its dual RJ-11 bracket ports (one for the incoming line, one for a pass-through phone). The card is labeled model 5660US and hardware revision V1.S10, and carries UL and CSA safety certifications.

Applications

ISA-bus dial-up modems like the Practical Peripherals 08-02762 were a standard component in desktop PCs throughout the mid-to-late 1990s and early 2000s, when dial-up internet access over the public switched telephone network (PSTN) was the dominant home and small-office connection method. The 56K V.90 standard, introduced in 1998, represented the peak speed available over analog phone lines and was widely adopted before broadband displaced dial-up. This card fits any PC with a 16-bit ISA slot — common on 486-era and Pentium-era motherboards — making it relevant today for vintage PC restoration, legacy industrial or embedded systems that use a PC with ISA slots for dial-up or fax communication, and collectors building period-correct machines. Practical Peripherals was a Canadian manufacturer known for reliable, FCC/UL-certified modem hardware sold across North America during the ISA modem era.
