- #3: SmartPort Bus Architecture
-
- Revised by: Matt Deatherage November 1988
- Written by: Mike Askins March 1985
-
- This Technical Note formerly described the SmartPort Bus architecture, but
- this information is now documented in the Apple IIGS Firmware Reference.
- _____________________________________________________________________________
-
- Do not be confused by the name "SmartPort Bus" architecture. The information
- in the Apple IIGS Firmware Reference describes the mechanics of how devices
- interface with the disk port on a IIGS or IIc and with the UniDisk 3.5
- Interface card on a ][+ or IIe. It is not necessary to understand this
- information to use SmartPort firmware calls, nor do all devices which have
- SmartPort firmware necessarily have to connect mechanically through the disk
- port or UniDisk 3.5 Interface card.
-
- The physical or electrical side of the hardware is called the "SmartPort Bus,"
- while the firmware protocols are called the "SmartPort Interface." Although
- the term "SmartPort" can refer to either or both parts, it is most often used
- to refer to the SmartPort Interface. Only those developers who are designing
- products which will attach to either the IIGS or IIc disk port or to the
- UniDisk 3.5 Interface card need be concerned with the SmartPort Bus
- architecture. Software developers need not learn about the SmartPort Bus
- architecture to use the SmartPort Interface firmware.
