Punches are added or removed, depending upon whether a hole is to be punched in a certain location. When all punches are in place the (guessing) lever is pulled and a cam drives the punches through the card into the die. Even this method is pretty darn slow. You would be working for a long time to make up a set of thousands of cards. Now there was a guy selling some cards on Ebay a year or so back--he was in California. I don't know if he has any cards left. |

They were small steel desks full of better make that a model "026", and "029". There was also a model "129". the 026 and 029 were distinguishable by the _round_ keys that stuck up from the keyboard, like a forest of dowels. The "129" had a contemporary-looking keyboard. with a grid of square keys. mechanical and electrical parts that no one wanted, so they were scrapped for the steel frames and made into small work benches. I don't know anything about the cardmatic, but if it uses a 'standard' Hollerith-style punch-card format 'card', then I know where _lots_ of "surplus" card-maker devices would be available. _Everywhere_ that governments used "punch-card *VOTING*MACHINES*". You could even make up a 'ballot form' that had a crib-sheet on it for what each hole in the card meant. grin |
