Applications
The Everex EV-657 Micro Enhancer Deluxe dates from the mid-to-late 1980s, the era when 8-bit ISA was the dominant expansion bus in IBM PC/XT and AT-compatible desktop computers. Video enhancer cards of this type were used to drive external monitors or video output devices via standard D-sub connectors, and were common in business and productivity environments running DOS-era software. The EV-657 is a sought-after legacy component for collectors and technicians restoring period-correct IBM PC/AT-class machines, and for anyone maintaining vintage DOS workstations that require original ISA video hardware. Its 8-bit ISA edge connector makes it compatible with the widest range of vintage PC/XT and AT motherboards.
This Everex EV-657 Micro Enhancer Deluxe 8-bit ISA video card has been inspected and appears to be in good used condition. It has not been powered up or tested at our facility. The board shows typical light wear consistent with previous use and age — no cracks, broken traces, or missing components are visible. The bracket and both connectors (DB25 and DB9) appear intact.
