IBM 129 Card Data Recorder
|IBM 129 Card Data Recorder, circa 1971
||129, Model 3
||Transistors, FET memory, SLT cards
||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.
||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. Also,
