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.
