1988 called and wants it memory tagging back https://www.devever.net/~hl/ppcas !

But yeah this was support for a the longest time by IBM basically. It's nice to see it's getting more widespread.

Nitpick: The AS/400 in 1988 didn't use the PowerPC. I believe it had it's own proprietary memory with tag bits included.

The first RS-64 with the PowerPC AS extensions came out in 1995.
