Macintosh PowerBook Duo 230: Technical Specifications
You may have solved this problem already. If not, do you have a PowerBook Duo floppy adapter and the external HDI-20 floppy disk drive (for 800K and 1.44 MB floppies)? See http://download.info.apple.com/Apple_Support_Area/Manuals/powerbooks/0306074APB2 00UG.PDF (page 31). That would allow you check whether it is possible to start up from a boot floppy (such as Disk Tools for this computer, or a Network Access disk (http://download.info.apple.com/Apple_Support_Area/Apple_Software_Updates/English -North_American/Macintosh/Utilities/Network_Access_Disk_7.5.sea.bin).
With access to a PowerBook Duo MiniDock (page 30 in the aforementioned manual), one could additionally connect (for example) a SCSI Zip 100 drive for testing purposes.
