Ah true, so 4 decades now. As far as I know, they switched to a quite radically different architecture (PowerPC) albeit with some added hardware features to improve performance of the result (although these may have been less about the shipped intermediate code in general, and more about the specific single address space nature of the system.

Reminds me of the old quote "When I was a boy of fourteen, my father was so ignorant I could hardly stand to have the old man around. But when I got to be twenty-one, I was astonished at how much he had learned in seven years."

Also applies to software and hardware designers of recent few decades when they learn more about the discoveries and accomplishments of the earlier years.
