The MVME147 series is a family of VMEbus single-board computers. The on-board resources and peripheral controllers eliminate the need for additional modules in the VMEbus backplane thus reducing costs and freeing up valuable bus slots for additional functions.

The MVME147 series features an MC68030 enhanced 32-bit microprocessor. The MC68030 was the first general-purpose microprocessor with on-chip cache memory for both instructions and data, which increases the processor’s efficiency by 20 to 40 percent. The MC68030 features a complete memory management unit (MMU) that provides the software protection and virtual memory functions critical to many applications.
