Simtec Hydra

The Hydra was designed to take up to 4 additional CPU cards and to schedule a RiscPCs resources between them. Because RISC OS is not designed to support multiple processors, Simtec produced an interface module which could be used by multi-processor aware applications and allowed them to use the additional CPUs. The Hydra was killed off by the arrival of the StrongARM CPU because a single StrongARM CPU was faster than a fully populated Hydra. In 2003 Simtec sold off their remaining stock of Hydras in a clearance sale., at the time Simtec were quoted as saying that a Hydra with 5 ARM710 CPUs was slightly slower than a strongARM CPU.
