Description
Western Digital WD6-VR 16-bit MFM Floppy Disk Drive Controller Card
The Western Digital WD6-VR is a classic 16-bit ISA expansion card that provided simultaneous control of floppy disk drives (FDD) and hard disk drives (HDD) in IBM PC and compatible systems during the 1980s and early 1990s. This controller implemented the MFM (Modified Frequency Modulation) encoding standard, which was the dominant data interface for both floppy and hard drives of that era.

Applications
The WD6-VR was a workhorse controller for personal computers and small business systems throughout the 1980s. It enabled users to connect and control both 5.25-inch and 3.5-inch floppy drives alongside MFM-encoded hard drives, with capacities ranging from 10 MB to 100+ MB depending on the drive model. This unified approach eliminated the need for separate controller cards. The card was widely used in IBM compatibles, particularly early 386 and 486 systems before IDE and SCSI became the dominant standards. Today, this controller is essential for restoring or maintaining period-correct vintage computer systems, both for collectors and enthusiasts working with legacy IBM PC hardware from the 1980s and early 1990s era.
This Western Digital WD6-VR MFM controller card has been visually inspected and appears to be in good used condition. It was pulled from a working vintage computer environment where it was previously in active service. The card shows typical age-related wear consistent with 1980s-era computing hardware.
