| 7 | This is a Linux ppdev userspace driver for a small card reader made by |
---|
| 8 | Nixdorf, equipped with the buffer board 377.01. This board encodes the |
---|
| 9 | 12 bit punch card code (H code) to 8 bit, by compressing row 1 to 7 to |
---|
| 10 | only 3 bits. |

| 13 | The connection is established via a self made cable from a pseudo standard |
---|
| 14 | Siemens plug to IEEE 1284 and to the power supply of the card reader. |
