| Wright Line Model 2600 Punch, circa 1970 | |
| Notes: | The Model 2600 punch is manually operated, and has 13 keys to punch holes in each of the 12 card zones, plus a Space key. Pressing a numbered key will punch a single hole in that zone, and advance the card by one column. Multiple zones may be punched by holding down the Space key while pressing number keys. These punches were found in computer centers in the '70s, to provide a quick method of punching a corrected card, or replacing a card with rough edges. |
