| Just came across a Tandy 1000 sx and pulled the motherboard. It has an amd 8088 and I was wondering if any of the other chips are "collectible". I will post pics later this evening. I also saw an older pc so I took that motherboard as well, that one had a Cyrix 6x86! My first Cyrix! I am very excited |

There are lots of Cyrix 166's on the internet. If you would have had a 150+, 120+, 100+ or 90+ they are more uncommon. The one you have looks to be a earlier one because it says "6x86P" and Cyrix was forced later to have "6x86PR" on them that stood for the "Performance Rating" system. Does it work?

| I don't know if it works. I could try to rig up something to power the motherboard but I am not sure if I have the proper gear to do it right. |

All it would take is an AT power supply, or an ATX power supply, and some custom wiring. |

| Don't rig anything up. Get the proper AT power supply otherwise you will just do damage. On Ebay these chips range from about $5-$15 depending on condition (works). |

It's perfectly safe to convert between ATX and AT. There's published diagrams everywhere on the Internet. It's just a matter of pin-for-pin conversion. All the voltages are already there, you just have to mate it to a different connector. They even make plug-in adapters that you can get (eBay is a good source) that have an ATX socket on one side, and AT plugs on the other. |
