I actually liked programming IBM/370 assembler. It wasn't half bad once you got past EBCDIC. It was certainly better than the x86. It also was pretty much eternal. I think I still have my banana book somewhere. https://i.pinimg.com/originals/fb/85/89/fb85890d32df071cf842026e9d459803.jpg https://i.pinimg.com/originals/fb/85/89/fb85890d32df071cf842... http://cbttape.org/~jmorrison/s370asm/html/tut-REFSUM-001.html http://cbttape.org/~jmorrison/s370asm/html/tut-REFSUM-001.ht...

This is not just S/370 assembler, the real ancient parts are IBM 7074. See for example https://books.google.ca/books?id=3iEDAAAAMBAJ&pg=PA88&lpg=PA88&dq=%22IBM+7074%22+%22irs%22&source=bl&ots=A_DZmgVBL7&sig=2cAXb5oG_JypmSU_jCa5fqbPqaY&hl=en&sa=X&ved=0ahUKEwjpvuvM2qbZAhVGwWMKHdbXA0YQ6AEINjAD#v=onepage&q=%22IBM%207074%22%20%22irs%22&f=false https://books.google.ca/books?id=3iEDAAAAMBAJ&pg=PA88&lpg=PA... but I read some protocol docs that some of the data is still encoded as it was in the 7074.
