                       MISCELLANEOUS TECHNICAL NOTES

     Not all jumpers are installed. You must solder those that are not
    present. Do not combine single- and dual-speed floppy drives on the
   same controller card. This controller has a built-in low-level format
    program. To enter the progam run the DEBUG utility supplied with DOS
                    and at the prompt enter: G=CC00:5.
