Summary
| Description |
English: As long as I can remember, my father had this tie clip. I believed that it was his name in some punchcard format. Not long after he passed away, in December of 2008, this tie clip came into my possession, and I noticed that there were a lot more bits on it than it would take to encode anyone's name. It didn't take much research for me to realize that it didn't match any known punchcard format that I could find. eventually, I found Wikipedia:File:IBM-026_wireplate.jpg on the wikipedia:Keypunch article— a picture of an almost-identical metal plate, with the same binary pattern. as it happens, this plate is apparently a part from a 1940s- or 1950s-vintage IBM-26 keypunch machine, a rather primitive Read Only Memory (ROM) containing data for printing characters in a 5×7 dot matrix. I'm uploading this image, now, because I think that the Wikipedia:Keypunch article could use a better-detailed image of this plate. The extant image is more “natural” showing the part more in its original form, without it having been made into a piece of jewelry, but my image gives a better view of the actual binary pattern stored on it. |
