Aeon Systems Inc, an Albuquerque, New Mexico-based maker of real-time VME distributed hardware and software running in Digital Equipment Corp environments, is beefing up the Alpha AXP line it introduced last spring, in response to what it regards as an overwhelming interest in Peripheral Component Interface bus. The new model VMEAlpha64/XP uses a 275MHz 21064 Alpha AXP RISC processor and contains an Intel Corp Peripheral Component Interface bus. It sports a two-board 6U module with optional 80960 RISC input-output co-processor, D64 transaction support, configurable cache and memory, and a Peripheral Component Interface bus for high-performance Ethernet, SCSI-2 and VME bus interfaces. One board contains the compute engine secondary cache and local memory, while the other houses the PCI local bus. The machine is downwardly compatible with the 150MHz Alpha64/SP so that designers will not lose on their investment in OSF/1, Fortran, Ada, C++ and other software developed for older Alpha systems. The XP will work with both complex and RISC VMEbus processors. The XP performs at up to 550 MIPS and is targetted for use with medical and industrial imaging, telecommunications and military-aerospace applications. It is priced at $12,000.
