How is the SVD connected to the floppy cable, and what do the different connectors do?
The SVD initially comes with two different edge-card connectors that connect to the left-side 34-pin header of the SVD. It is extremely important that you use one of these connectors. Please do not try to plug a floppy cable directly into the 34-pin header. The SVD uses one of the 34-pin header pins to deliver +5 to the terminated connector. The “straight through” connector is used when there is a terminated floppy drive or another SVD physically on the floppy cable. It includes no termination. The “terminated” connector has a resistor network on the bottom, and will effectively terminate the floppy buss. This should only be used when there is no other device terminating the floppy cable. It is always safer to try to straight through connector first. Note, too, that the floppy or SVD with termination should be the last device on the cable (the farthest away from the computer).
