Simple Meltdown-Spectre detector from Gibson Research

[6502coder]

Gibson Research has a simple tool that gives you a yes/no answer as to whether your system is vulnerable to Meltdown-Spectre.
This is a Windows tool. It will run under Wine, with the limitation that it will be able to tell you if your CPU is vulnerable, but it will not be able to assess your OS. See the web site for full details.
