(Apple II+ & up, 64K Required)
Data Transfer Rate: 128-256K / Sec.
This card, is the most common card, is made by Apple Computer. This card has been
replaced by a faster model, the DMA or High Speed SCSI Card. This card can be used
in any slotted Apple II, or compatible and the Laser 128's expansion box. This card
under ProDOS 8 will only support 2 Partitions, for a total of 64 Meg. However, many
software products are available in the public domain that will let ProDOS 8 access
more than 2 partitions. In an Apple IIgs, GS/OS can recognize up to 40 partitions of
32 Meg each, thus allowing the use of a much larger drive.
