From the 9160A manual:

Quote:The 9160A takes its power directly from the Model 9100 Calculator. The only connection required is to insert the 9160A plug into the connector at the rear of the calculator.

Also:

Quote:When using other peripherals, such as the 9125A Plotter, in conjunction with the Card Reader always plug the 9160A signal connector directly into the 9100A Calculator. Insert signal connector from second peripheral device into the back of the 9160A connector.

This would suggest that peripherals are "daisy chained." If that card edge is the rear-facing connector on the 9160A, then I suspect someone has plugged something into it that damaged the card reader.
