    After cleaning and alignment, the punch card feed mechanism works very smoothly. More details: www.nycresistor.com/2012/01/15/ibm-129-card-data-recorder/

      Oh man, does this bring back memories. Had to use on of these beasts for my PL/I class back in the day. I hated it, i had cut my teeth on interactive terminals. Batch process was alien and foreign to me.

      These were the fancy one's that everyone wanted to use, instead of the 026.

      The 129 data recorder was the electronic version of the 029 card punch. A full set of data for a punched card was held in memory before being punched into the card. With the 029 and the 026 when you pressed a key it immediately punched into the card. Press the wrong key and the whole card had to be re-punched. I used to be an IBM customer engineer for these beasts in the late 60's and tested the 129 in 1970. Happy days!
