A colleague of mine who had been using a CDC 6400 as a graduate student took a job with IBM in NY. He took some useful information with him in CDC column binary format; two CDC Display Code characters per column. He set himself his first IBM Assembler exercise reading the data and converting to EBCDIC.
When he got there, he was dismayed to be told that the CDC binary format could not be read on IBM equipment, at least not without a (separately priced?) feature. (Hardware? Software?) True?
