PA-RISC computers used the PDC for Boot ROM.| www.openpa.net
PA-RISC processors are RISC processors developed by HP for its HP 9000 computers – from 32-bit PA-7000 of the 1990s to 64-bit PA-8900 of the 2000s.| www.openpa.net
HP 9000 PA-RISC computers are based on HP PA-RISC architecture and processors. Most of the chipsets and system designs used were custom HP for its servers and workstations.| www.openpa.net
PA-RISC computers used error codes on their LED panels to signal system problems.| www.openpa.net
PA-RISC computers used proprietary HP expansion cards for EISA, GSC and PCI.| www.openpa.net
Comparing the speed of CPU architectures is a very complex and sometimes futile undertaking, as the platform around processors might be much more significant than the actual ISA. Still, it is historically interesting to see how different RISC architectures fared against each other in the RISC/Unix world of the 90s. While PA-RISC processors were usually faster than their competition at the same clock speed, they were expensive to fabricate. Their platform, HP 9000 with PA-RISC and HP-UX, was u...| OpenPA.net
PA-RISC computers used many standard SCSI controllers and chips, mostly from NCR.| www.openpa.net
HP PA-RISC 32-bit computers and many 64-bit PA-RISC computers used HP-designed CRX and Visualize video adapters.| www.openpa.net
PA-RISC is a Reduced Instruction Set Computing (RISC) architecture from HP developed during the 1980s and sold until the early 2000s.| www.openpa.net
The popular HP 9000 family of Unix systems included many different types of PA-RISC servers, workstations and mainframes between the 1980s and 2000s.| www.openpa.net
PA-RISC computers used custom HP and industry standard bus designs in HP 9000 workstations and servers.| www.openpa.net
PA-RISC computers used mostly proprietary HP chipsets and system designs in HP 9000 systems supplemented by third-party chips.| www.openpa.net
