Make sure your PSU is powerful enough to power both your Amiga 500 and the A590, some of the cheaper made models of PSU might not be able to power both + an older SCSI HD. Should be less of a problem if you use one of the newer SCSI to CF card adapters. Not much more to say, it just works, tested it attached to Amiga 500 with kickstart 1.3 but have also used it attached to a 500+ with kickstart 3.1. Check pictures for detailed condition. DMA SCSI and XT IDE controller.Both SCSI and XT IDE mode can work simultaneously. Autoboot ROM - autobooting requires at least Kickstart 1.3. Time-out switch for drives which spin up slower than 30 seconds. 50 pin internal SCSI header. Internal 40 pin XT IDE header (8 bit only). Sixteen DIP sockets accept 0.5, 1 or 2 MB RAM. Needs 256k×4 DIPs, 120 ns or faster.
Place for a 3.5 hard disk inside the case. Hard disk activity LED - it can be toggled by jumper to show SCSI or XT-IDE activity. Connects to the side expansion port, no passthrough connector.
External power supply - turns on automatically when the A500 is powered up. Autoboot ROM: ON - enable. Time-out: ON - enable long wait period for drive.
