Revised by:    Matt Deatherage                                  November 1988

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).

        Type   Device
        $00    Memory Expansion Card (RAM disk)
        $01    3.5" disk
        $02    ProFile-type hard disk
        $03    Generic SCSI
        $04    ROM disk
        $05    SCSI CD-ROM
        $06    SCSI tape or other SCSI sequential device
        $07    SCSI hard disk
        $08    Reserved
        $09    SCSI printer
        $0A    5-1/4" disk
        $0B    Reserved
        $0C    Reserved
        $0D    Printer
        $0E    Clock
        $0F    Modem

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
