I uploaded the last batch of documentation i have on the WD9000.
Goodies are at ftp.dreesen.ch/WD9000
Note that there are now early and later versions of the schematics.
Ref F6 of the schematic is what i put up earlier, I now combined them into a single PDF
file.
The earlier set E5 does show a different interrupt controller.
Al, feel free to copy if it is of use to you.
and now to get a 8 inch floppy imaging system set up.....
