Hi JamesC,
The 1571 is set with switches up to the 8 device number an working perfect with my C64. No other drives attached at the same time and the SD2IEC is working ok with the C64 as drive 8.
Attached a picture upon testing.
Are you sure about the bus activity? According to the C16 schematic from the service manual the serial port is controlled by the 8501 CPU. Now and do not know how a potential damaged 8501 can just make the serial bus to stop working and the rest looks ok.
