The ACTIS Computer VSBC-6862 is a 6U VME CPU module built around the Motorola MPC8260 PowerQUICC II processor, delivering 280 MIPS performance at up to 200 MHz. The dual-processor architecture pairs a PowerPC core with a dedicated RISC communication processor (CPM), enabling independent handling of networking and communication protocols alongside system operations. Designed for industrial and embedded applications requiring reliable computing in demanding environments, this module integrates comprehensive memory, connectivity, and expansion capabilities into a single VME form factor.
