You are correct about the 029. However in the 1401 machine room at CHM there is an 026 which was the correct keypunch for the era. OP could have used that but would have had to punch it manually -- not fun! The 029 used is, as noted in the article, relay-driven from a USB port, so he could just dump the working executable from the simulator. Of course for full authenticity he SHOULD have manually punched the source deck on the 026, fed it into the 1401 for assembly using the 1402 reader, and had Autocoder in the 1401 punch the executable deck on the 1402.
