I think it's just poorly worded (or they indeed confused it with AS/400), and what they really mean is while technically yes, IBM mainframes run machine code that has been kept compatible for decades, today lots of old instructions are microcoded and the overall CPU architecture is so different that it amounts to recompilation in hardware. So the particular choice of assembler language doesn't really matter anymore.
- p_l 6y agoI'd suspect it's a bad interpretation of how microcoded computers work, as on first contact they do sound like virtual machines like that.
