IBM 129 Card Data Recorder, circa 1971

Model: 129, Model 3
Features: The 129 doesn't use a program drum like the 026 and 029 machines, but instead has internal memory to store up to 6 programs read in from cards. It also works as a verifier.
Notes: This keypunch arrived in fairly decent cosmetic condition, and included all the covers. It didn't require too much work to get it operational. I replaced the main V-belt, which was severely cracked, installed a new ribbon, oiled and greased many points suggested by the tech manual, and cleaned the rubber rollers with Rubber Rejuvenator. I also had to align the upper card guide, and the resultant punched card lines up perfectly with the Card Registration Gauge. It feeds, punches, prints, and seems to be 100% operational. I've scanned the 129 Machine Description manual.
