The Apple II High-Speed SCSI Card is a DMA compatible SCSI interface for the Enhanced Apple //e and IIgs. It was that last SCSI interface that Apple released for the Apple II, improving upon the earlier Apple II SCSI Card.

The card is sometimes referred to as the "Sandwich II Card" due to the text SANDWICH II printed on the circuit board.

Apple SCSI cards do not supply termination power to the SCSI chain. If no other devices on the chain can supply termination power, the card must be modified to provide it by installing a single diode on the card. Instructions for making this modification are in the Hard Disk & SCSI Interfaces section of Rubywand's comp.sys.apple2 FAQ.
