Some of the processors I've worked with over the past thirty years...

The 21064 ALPHA EV4

A DEC/digital 21064.
The first of the ALPHA processors.

This is the 64 bit EV4 Alpha RISC chip. As found in some of the decstation systems here
at It's a 64 bit superscalar processor, with 32 bit instructions. With an integer,
a floating point, and a load/store unit. One of the new features of this design is the extendable
instruction set! Introduced in 1991 It was the fastest, and best processor in it's day.
