Sorry for the delay. I didn´t completely understand your last questions. What are the differences of DB vs. DA? In fact the connector has exactly the same outer dimentions like the old Mac Video connector, you are right. I compared it with my old 14" from my PM6100. Of course there are 26 pins at the Gigafile.

And I do not get as well what you plan to do with the Powerbook. Would you like to hook it up to the external "HDI 30-SCSI II" ? If you really like to have it without it, just drop inventronic a mail. I am sure they will do one for you without at the next production run.
