Anyone have a collection of the Alpha 21064 / 21164 / 21264 CPU's?
I would love to have a list of how many there were and any links
to websites that may have pictures of them.
My latest finds include more "Proto" chips and my first "ES" chip!!  |

alpha chip is very beautiful
but most of them are soldered
it is quite difficult to find NOS one or pull one.
Is there socket for alpha chip? |

| I have a few working alpha systems. And yes, there are sockets for alpha chips. I had mitsubishi made 21164pc-533. Also had samsung made 21164a-600 and -666 chips. One day, I'll pull the cpus out of the systems and take pictures... |

| I have become pretty adept at desoldering these chips. |

I have (69) Alpha 21064, 21164 and 21264's in my "collection".
Some socketed but most desoldered. From EV4's to EV68's.
Anybody know what the markings on these chips that say
KA, KKA, KKB, K3, NKA, etc. stands for?? |
