Conexant VO-94V-0 16-Bit ISA Internal Dial-Up Modem Card V.90 56K RJ-11

Conexant VO-94V-0 16-Bit ISA Internal Dial-Up Modem Card V.90 56K RJ-11

The Conexant VO-94V-0 is a 16-bit ISA internal dial-up modem card designed for desktop PCs equipped with a standard ISA expansion slot. It uses Conexant's controller chipset and conforms to the V.90 standard, supporting speeds up to 56 Kbps over standard analog telephone lines. The card is a half-length design with a full-height bracket and features two RJ-11 ports on the bracket — one for the incoming telephone line and one for a pass-through handset connection. Sold as a bare card with no accessories, drivers, or software included.

Applications

ISA internal modem cards like the Conexant VO-94V-0 were the standard method for adding dial-up connectivity to desktop PCs throughout the 1990s and into the early 2000s, before broadband made them largely obsolete. The ISA (Industry Standard Architecture) 16-bit bus was a fixture of the PC-compatible world from the mid-1980s through roughly the late 1990s, present on virtually every AT-class and early Pentium-era motherboard before PCI took over as the dominant expansion standard. Cards of this type were used for internet access, fax transmission, and bulletin board (BBS) connectivity. Today, ISA modem cards like this are sought by vintage PC enthusiasts restoring period-correct systems — particularly machines running MS-DOS, Windows 3.x, Windows 95/98, or early Windows NT — and by hobbyists who need a working modem for retro computing projects or legacy industrial systems that still rely on dial-up communication. Compatibility is limited to systems with a 16-bit ISA slot; PCI-only and PCIe motherboards will not accept this card.
