The 486-CCV is a distinct, compact motherboard design that gained notoriety in the mid-1990s as a high-integration "value" solution for the 486 platform. The "CCV" designation typically denotes a board featuring a combined Cache, Controller, and VESA Local Bus (VLB) implementation, aimed at users who wanted decent performance without the cost of high-end, dedicated chipset motherboards.
Processor Support: Designed for the late-stage 486 lifecycle, supporting the Intel 486DX2, DX4, and frequently the AMD 5x86 upgrades.
Memory/Cache: These boards typically featured 72-pin SIMM support and 128KB or 256KB of integrated L2 cache (usually "Write-Through" by default, with jumper settings for "Write-Back").
The Clone Reality: The 486ccv was a favorite of the "white box" industry. If you were buying a pre-assembled computer from a local electronics store in 1995, it likely had a motherboard sharing this design. It was neither the fastest nor the most stable, but it was highly compatible with the vast array of VLB expansion cards that flooded the market at the time.
