Description

The Sonus / Performance Technologies / Ziatech ZT 8952 / 8953 IDE Interface and Mounting Board is an Integrated Drive Electronics (IDE) interface for the STD 32 buses that support PC-AT technology disk drives. The ZT 8952 also serves as a mechanical mounting board for the drive, allowing for a modular plug-in unit for the STD bus. The ZT 8952 supports 2.5 inch disk drives, while the ZT 8953 supports 3.5 drives, both mounted directly to the board. The ZT 8952 / 8953 is also available with no drive mounted (ZT 8952-0 / ZT 8953-0) for applications that require remote mounting of the drive. Cables are restricted to 18 inches in length from controller to drive. The ZT 8952 / 8953 will support up to two drives.

Mechanically, the ZT 8952 8953 is compatible with the STD 32 Bus Specification. The ZT 8952 / 8953 supports 8 MHz and 5 MHz STD-80 timings, as well as STD 32 transfers. Both 8-bit and 16-bit transfers are supported under STD 32. The ZT 8952 / 8953 will support up to four Mbytes/second transfer rates on the backplane (one word every four 8-MHz cycles.) The actual transfer rate will vary with the host CPU and drive used.

The PC-AT IDE interface is a 16-bit interface only when transferring data through the 01F0h data register. The ZT 8952 / 8953 supports full 16-bit transfers for STD 32 processors. For 8-bit processors, the ZT 8952 / 8953 will byte pack and unpack the 16-bit IDE transfer to provide 8-bit STD bus transfers. All signals are fully buffered between the STD bus and the IDE interface. The IDE interrupt may be jumpered to drive INTRQ*, INTRQ1*, INTRQ2* (CNTRL*), INTRQ3*, IRQx (STD 32), or one of five frontplane interrupts. Some versions of Ziatech's STD DOS require the use of interrupts.
