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..... Jos
