  This is not typical. Most older FDC cards drive all
the floppy interface 
 lines with 7438 (or similar open-collector gates) devices. More modern 
 ones put everything into the same ASIC as the floppy controller logic 
 (and maybe other things as well). 
Right.   The Amiga is atypical.  This PeeCeeoid is industry standard inside.

   I'm trying
to make a cable to hook up floppy drive to a proprietary DB-25
 external connector on a sealed PeeCeeoid.  
 Sealed? No such thing :-)... That's what screwdrivers, torx drivers, 
 hammers, etc are for.. 
Of course.  That's how I got as far as I did - I disassembled the box, located
a 34-pad spot on the motherboard where a floppy connector *should* go, then
used a VOM to trace the wiring between the internal 34-pin connector and the
external 25-pin connector.  What stumped me was a lack of /MOTORON (pin 16).

All is now well.  It boots Linux just fine.  Thanks.
