摘要
提出一种不含DMA的 Z80微机倍密度软磁盘控制器接口电路,它以 FD1793为核心,通过中断方式完成主机和软盘机的信息交换,实验证明该接口具有成本低、可靠性高和编程简单等优点,易于应用微机系统中。
This paper presents the new design of FDC technique for Z80 microcomputer.Based on LSI FDC 1793. the communication between CPU and FDD is processed by interruption method and the DMA controller is waivered.lt is proved that the interfacing circuit has high realibility and is easy to find applications in microcomputer systems.
