Amiga Hardware DatabaseManufacturer Supra, USA | Date 1987 | Amiga A2000, A3000, A4000 | Interface Zorro II | Autoconfig ID 1056 / 3 |
- SCSI Controller
- internal hard disk controller for the Zorro II bus
- features a 5380 SCSI Controller IC and a Motorola MC68440 DMA Controller IC
- uses DMA transfers
- autoboot ROM - autobooting requires at least Kickstart 1.3
- 50 pin internal header
- DB25 external connector
- hard disk activity LED connector
- three mounting holes for attaching a SCSI to ST-506 adapter
- Notes
- one example of the early DMA designs, uses a non-DMA SCSI controller together with a 68k DMA controller as I/O transfer engine - the performance was lacking, therefore for the later generations, Supra switched to a design with programmed I/O (PIO) with the same SCSI controller chip which resulted in increased CPU load (no DMA transfers)
