Cards for Automatic Dialers Top row: Cards are physically identical but are marked for : 1. Rotary or 10-button tone sets (digits 1-0 only) 2. 12-button tone with star and diamond keys. 3. 12-button tone with * and # keys Bottom: 16-button Card Only one row of sprocket holes and rectangular (not circular) holes. Does anyone know what dialer uses this card? Autovon 16-button Card (not shown) Looks like cards on the top row, but is wider to accommodate an additional row of holes. All use a 2 of 8 code: 2 punches in a column for each digit. A final punch in the "STOP" row tells the dialer when to stop. Once punched, the card is a read-only storage device. |
