Apple II High Speed SCSI Card
|
|
|
|
Copyright 1990, Apple Computer, Inc.
|
|
|
|
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 Ñ 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.
