The Apple II SCSI card significantly increases data transfer speed between Apple II personal computers and SCSI devices such as hard disk and CD-ROM drives. The card works with the Apple IIe and Apple IIGS personal computers and is compatible with all SCSI devices. It provides the fastest data throughput possible for Apple II users. Using direct memory access (DMA) data transfer, if offers speed improvements of up to 10 times faster than that of the previous Apple II SCSI Card, which it replaces. The new card also comes with software utilities for use with hard disk and CD-ROM drives.
Users with a hard disk drive and the new SCSI Card will see a significant speed improvement when using large software applications, such as AppleWorks GS, or large data files.
Features and benefits include:
% DMA Data Transfer -- on the Apple IIGS computer, data can be transferred at a rate of up to 1MB per second. On the Apple IIe computer, data can be transferred at a rate of up to .5MB per second. There are four switches on the card. One is used to set DMA on or off. The other three are used to set the SCSI identification number of the card Q each SCSI device, including the computer, is set to a unique number from 0-7.
% SCSI Compatibility -- compatible with all SCSI devices, the Apple II High-Speed SCSI Card requires only that device-specific applications and drivers be installed on the system. The card comes with drivers and applications for hard disk and CD-ROM drives.
% On-Board Terminator -- simplifies setup for the user when connecting SCSI devices to the computer.The user simply places one terminator at the end of the chain of SCSI devices.
% Utilities -- comes with improved hard disk utilities that partition and verify hard disks, and backup information. The Partition and Verify utilities take advantage of the improved firmware commands for hard disk drives. The Backup utility is now able to handle the resource forks that are part of the IIGS files. These are all ProDOS utilities and can be used by both Apple IIe and Apple IIGS users. In addition, the CD-ROM desk accessory for the Apple IIGS, CD-Remote, comes with the card.
System Requirements:
The Apple II High-Speed SCSI Card works on an Apple IIGS personal computer or an Apple IIe computer with a 65C02 microprocessor (note: older Apple IIe's, that have a 6502 microprocessor, will need to upgrade with an Apple IIe Enhancement Kit). The Apple IIGS requires a 3.5-inch disk drive, while the Apple IIe requires either a 5.25- or 3.5-inch disk drive. Both require a device with a SCSI port, appropriate SCSI cabling, and one SCSI terminator.
There is no upgrade program for owners of the previous Apple II SCSI Card.
