I don't think Macs would be a great platform for running a k8s cluster, but the power efficiency alone makes them a curious alternative to explore.
It was *not* common in mid-90s. x86 was commodity hardware - home PCs, early NT workstations. PHP was still written in Perl. Linux was a few years old - industry veterans (e.g. Greenspun) were throwing rocks at it.
Yes, the x86 platform was documented - through reverse-engineering efforts. Compaq was the first to produce PC clones, to IBM's great disdain.
Don't get me wrong - you're probably better off running Ampere. Just don't dismiss commodity hardware.
“I wonder why people keep writing that PHP was ever written in Perl. It never was. #php”
The PHP history page at one point claimed it was:

He may have had some Perl scripts on his computer before the 1.0 C release, but that’s a far cry from “PHP was written in Perl”.
