Storage bins for cards, separated by index dividers.

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.
