GVC 126B1640000A Internal ISA Fax Modem Card 56K PnP Jumper Configurable PC

The GVC 126B1640000A is a 16-bit ISA internal fax modem card designed for desktop PCs equipped with an ISA expansion slot. It supports both Plug-and-Play (PnP) and manual jumper-based IRQ/address configuration, making it flexible for systems that may not fully support PnP BIOS. Two RJ-11 ports on the rear bracket provide line-in and phone pass-through connections, and a 3.5mm speaker jack allows audio monitoring of call progress.

• Includes card only — no driver disks, software, or ISA fax modem cards like the GVC 126B1640000A were standard equipment in mid- to late-1990s desktop PCs, bridging dial-up telephone lines to the computer's expansion bus. They were used for dial-up internet access, fax transmission and reception, and BBS connections under DOS, Windows 3.x, Windows 95, and Windows 98. The ISA bus was the dominant PC expansion interface through the mid-1990s before PCI modems became mainstream around 1997–1999; cards like this one represent the tail end of the ISA modem era, some supporting both jumper configuration (for older systems) and PnP (for Windows 95/98 systems with a compatible BIOS). Today these cards are sought after by vintage PC enthusiasts and collectors restoring period-correct 486 and early Pentium-era machines, and by hobbyists operating dial-up BBS systems.
