http://avitech.com.au/?page_id=2060 MFM Hard Drives

restoring vintage Soviet MFM Hard disk drives. Most famous of them, called SM5508 (??5508) used MC68705P3 chip.

Most of Soviet MFM Hard Drives were just replicas of American units. Of course they all work with WD MFM cards. Same protocols and signals. Sometimes they even used western parts.

You can see some pictures ot this page. Sorry but text is in Russian.
