This unit
The Abaco Systems / Radstone PME 68-42 is a VME Single Board Computer engineered for real-time applications requiring intensive I/O and computation. Its dual-processor architecture pairs a Motorola 68040 primary processor with a dedicated Motorola 68020 I/O processor operating at 20 MHz, enabling parallel processing and reduced latency in VMEbus environments. The "Freeflow" architecture maintains multiple independent internal and external data paths to minimize bus contention and I/O conflicts.
