I compare the manual of the different brands and types of S-100 hard disk controllers with the device driver i have.
The Morrow HDC/DMA is the only one that fits. The complete command/data transfer goes over the RAM.
Two I/O addresses are only exists for Reset and Start operation (54H & 55H).

I got a HDC/DMA controller on eBay. If this work with my current driver i try to implement the S-100 dual IDE controller in the driver.
