Emerson / Motorola / Force Computers SYS68K CPU-40B/16-01 Single Board Computer

The Emerson / Motorola / Force Computers SYS68K CPU-40B/16-01 is a VMEbus-based single-board computer built around the Motorola 68040 microprocessor operating at 25 MHz. It integrates 16 Mbyte shared DRAM with burst read/write capability, 128 Kbyte battery-backed SRAM, and 128 Kbyte Flash EPROM with on-board programming. A high-speed 32-bit DMA controller (FGA-002) manages data transfers across shared memory, VMEbus, and I/O subsystems.
