What is your oldest working cpu

PowerPC 603e 200mhz from a Mac clone dating back to 1997. Parents business used to have it to calculate job costs. Used it up until 2008. It's in my basement now.
 
My Dad's tandy TL2/1000, I think it runs at either 2-4 Mhz. He refuses to switch over 100% to the P4 2.0ghz system I put together for him. Crazy!
 
Dual Athlon MPs on an iWill e/w 1GB RAM. CPUs are WC & OC ... been running forever. Never shut off although the HD is showing its age. Since it is runnng W2K, it will probably get shutoff when the HD gives it up.

Oldest thing I'm currently running is a Phenom 9850. I've got an Athlon X2 5000 that works sitting in my closet, theres also an Athlon 3400 Clawhammer with working board that just isn't hooked up right now.

I've also got an Athlon 3500 and Core Duo T2500 in laptops that work, but currently are not used for anything.
 
Intel i8088. 4.77MHz, 8MHz Turbo mode. Just goes to show you thinking like the i7's "Turbo Mode" aren't anything new.

And no. I'm not kidding.

Shame on me my first cpu was the intel 386 dx 40mhz closely followed by the cyrix 166mhz

Intel never made a 40 mhz 386. All the DX40s are AMD chips.

Ah yes, the infamous turbo button that downclocked the CPU (when it was wired up properly). I don't know that you can really draw comparisons between the Turbo Mode of yore and today's Turbo since all Turbo Mode amounted to was running the CPU at stock speeds (deactivating Turbo Mode downlocked the CPU).

My k6-233's case had a turbo button on it, though why turbo buttons were still showing up on computer cases by the mid-late '90s, I'll never know. That case had a handy digital readout you could configure to display whatever frequency you liked regardless of whether or not the button was properly wired to the motherboard (and believe me, the mobo I had in that thing did not support Turbo Mode). Mine read 233 when Turbo was allegedly activated, and 23 mhz when it was not. I thought it was funny at the time.

Remember how in those days, chips pre-dated the "ZIF" socket, so processors were more-or-less permenently attached to the motherboard. On most of those AMD 386DX-40 boards, the CPU came soldered on, like today's Atom boards.

The only two machines I ever had that weren't socketed was a 386SX and a 486SLC. I do vaguely remember some Intel 486SX chips also being QFP-style soldered on chips too, but none I owned.
 
serial (one-bit) processor chipset made by Mostek:

Still have it and use it.
 
If this counts I still have a 20MB and 40MB seagate MFM hard drive pair in my junk box. Came out of an old 286 server. Still works!!!!!!!

The cool thing is you can operate them without lids and watch them work. New hard drives are so precise, there is no way to do this.
