Storing information by punching holes into flat media
On looms, mechanical music instruments, telex paper stripes
Before the 1970, programming and data entry was done - if not by manual entry on a switchboard - via punched cards. One line with up to 80 characters on one card: that made a nice pile for 300 lines of programming code or data.
The project has several branches:
Virtual Punched Card Museum
This is in its 2nd stage, with about 400 punched cards shown, distributed over a set of application areas. Still missing are the cards donated by american collectors, and the non-card items (paper stripe, loom ribbon, mechanical music media, hotel keys etc.
Key punch emulator
On the Internet:
- Cardpunch on kloth.net
- keypunch at masswerk.at
- 1964 IBM 029 Keypunch Card Punching Demonstration video
- IBM 026 emulator, but it must be compiled under Unix for the X Window system
The new emulator should be implemented in JavaScript. Desired features would be:
- Usage of the card images from the virtual museum
- Generation of an image which can be printed with proper diemensions
- Selection of code sets
- Overpunching
- Realistic sound of an IBM 029
- Usage of a tabulation card
- Precise dimensions
Punch Card Reader
Again, there are services on the Internet which do this, for piles of card images, and not too cheap.
- Punchcard Reader in Python; I could not get it running]
The emulator in JavaScript should habe the following features:
- Recognize the card in a larger image, which may be a bit distorted.
- Use front and rear images
- Selection of codes
- Show grid of theoretic hole positions

Paper Stripe Puncher
I still have a working Siemens Fernschreiber 100 with user manual. On my 70th birthday I got the connection hardware from daduke. The machine will punch manually, but it is rather slow. There is a video for the sound of a Siemens T100.
I also have 2 highspeed GNT 3601 punching devices sitting there since many years. The manual (in French) says on page 387:
Liaison perforateur GNT

You can see it in action.
