SmartPort #4
SmartPort Device Types

Revised by Matt Deatherage (November 1988)
Written by Rilla Reynolds (June 1987)

This Technical Note documents additional device types which the SmartPort firmware recognizes, but which may not be currently documented in the technical reference manuals which cover SmartPort.


The following is an updated list of possible SmartPort device types, extended to support an increasing variety of third-party peripheral products. A device type byte is returned as part of the Device Information Block (DIB) from a SmartPort STATUS call ($03).

It is likely that the SmartPort device type list will expand in the future. If you are developing a SmartPort device and do not see a suitable device type in the list, contact Apple II Developer Technical Support at the address listed in Technical Note #0.
