The world still needs mainframes and it still needs AIX and Solaris. The world still needs Z, POWER, SPARC.

Many machines use
speculative_execution and are susceptible to Spectre.
Unfortunately this may include the IBM Z system. Here is an article on Spectre changes to GCC for the system 390:

When I look through my own old hardware, the slower simpler machines seem safer.
I have an Intel Atom D510 machine whose cpu was released in 2010. It appears to be immune to Meltdown and Spectre. It was designed to operate at low power and apparently does not do speculative execution.
