The PowerNode 9080 was a dual processor 32-bit Superminicomputer produced by Fort Lauderdale, Florida based electronics company Gould Electronics in the 1980s. Its UTX/32 4.3BSD Berkeley Unix-based operating system was one of the very first multi-processor shared memory implementations of Unix, although the processors operated in a Master-Slave configuration with a Mutual Exclusion (MutEx) lock on all Kernel IO resources. Machines could be configured for either single or dual processor operation.
The machine itself was housed in a number of 19 inch rack cabinets and the main CPUs consisted of 18 boards of ECL logic. The resulting system was capable of benchmark performances up to 20 MIPS, a very high rating at the time. The PowerNode systems were a very close relative of Gould's real time computer systems running their proprietary MPX real time operating system. Only about two boards differed between the Unix-running PowerNode machines and the MPX-running real time machines. The most significant of these was the Memory Management board which had virtual memory mapping abilities in the Unix-variant but not in the real-time variant.
A smaller model of the PowerNode was also available in the form of the Gould PowerNode 6032 and 6040 systems which achieved a 7 MIPS performance similar to the contemporary DEC VAX-11/780 and VAX-11/785.
The PowerNode series was replaced by the Gould NP-1 series. When Gould was purchased by Nippon Mining, the computer division was divested on the instructions of the US Government for National Security concerns and became part of Encore Computer.
