- SCSI and ST-506 controller
- supports seven SCSI and two ST-506 devices at once
- the SCSI drives are controlled by the WD 33C93 IC
- the ST-506 drives are controlled by the Zilog Z80B CPU
- the 33C93 chip can be controlled by either the 68000 (default) or by the Z80
- DMA transfers are provided by the custom Commodore 8727 IC featuring a 64 byte FIFO buffer
- the Z80 CPU has 2 kB RAM to buffer commands from the Amiga, 8 kB PROM with driver routines and 1 kB RAM for storage of variables
- cannot autoboot
- does not support the SCSI Direct protocol
- does not support partitions and drives larger than 256 MB
- the ST-506 interface does not support 16-head drives
- 50 pin internal SCSI connector
- DB25 external connector
- hard disk activity LED connector
- on Zorro III machines the card only works if the driver and all the buffers are loaded into chip RAM
- A-Max II driver (hddisk.amhd)
