FDD 82 Pravetz, not a change with an integrated controller, so big like two times. Perhaps one reason that achieved 8D Pravetz 8 Pravetz OT Was (3 times less the price though) Never popularity.
In fact, there are two 8D Pravetz to drive. A (published schematics and magazines to "firmware for information) 82 Pravetz FDD and use an additional controller? Power supply was designed to develop there. 8D an operating system called DOS, Borislav Zahariev has been developed in Bulgaria by was.
Later, the factory is 8D, which twice the usual [Apple] disk controller and power supply in the large box was covered with FDD Pravetz specifically decided. He had been on the market over the production team! This revised version of the DOS disk 8D DIY uses.
