Trident 7343 Rev C1HK ISA VGA Card 512KB DRAM OKI M514260 Vintage DOS PC

The Trident 7343 is an early-1990s ISA VGA graphics controller card designed for 286, 386, and 486 class IBM-compatible personal computers. Built around Trident Microsystems' 7343 chipset, it delivers standard VGA output via a DB-15 connector and was a common, affordable graphics solution in the DOS and early Windows 3.x era. This example is revision C1HK on a full-length ISA card.

Applications

ISA VGA cards like the Trident 7343 were the standard graphics solution for budget 286 and 386 systems in the early 1990s, when ISA was the dominant expansion bus before PCI arrived mid-decade. Trident Microsystems was one of the most prolific VGA chip makers of that era, shipping chipsets to dozens of card manufacturers for use in everything from entry-level home PCs to business workstations running DOS and Windows 3.x. The 7343 supports the standard 640×480 VGA resolution at up to 256 colors and lower-resolution VESA modes, making it fully compatible with the DOS game and productivity software library of the period. Today these cards are sought by vintage PC collectors and retrocomputing enthusiasts building or restoring period-correct 286, 386, and 486 systems, and by hobbyists who need a simple, driver-free VGA output for older ISA-bus hardware projects.
