PA-7000 (PCX-S) processor


The PA-7000 was a 32-bit PA-RISC processor, version 1.1 architecture with a MMU, introduced in 1991. It was first used in the HP 9000 700 series workstations and later in some of the HP 9000 800 Nova servers. The PA-7000 was a multi-chip implementation with an external FPU.
