Last I looked the jumper blocks were near the center of the board, about 1 inch east of the power supply and floppy drive headers (next to the 6522 at U106). Cut the front one for U9, the back one for U10, both for U11. If you are going to install a switch, place it between the side of the jumper pad nearest the 6522 and ground. -- Fred Bowen uucp: {uunet|rutgers|pyramid}!cbmvax!fred domain: fred@cbmvax.commodore.com tele: 215 431-9100 Commodore Electronics, Ltd., 1200 Wilson Drive, West Chester, PA, 19380
