1. General Description

The MVME147‑024 is a high‑performance 6U VME64 single‑board computer, pin‑compatible with MVME147‑024A. It features the MC68030 32‑bit CPU @ 33.33 MHz (integrated MMU, 256‑byte unified cache) plus an MC68882 FPU @ 33.33 MHz for floating‑point intensive tasks. Onboard 32 MB DRAM with programmable parity (jumper‑selectable error detection for high‑reliability applications). Peripherals include AUI Ethernet, asynchronous SCSI (WD33C93, DMA), four EIA‑232‑D serial ports, Centronics parallel port, and battery‑backed 4 KB SRAM/RTC. Designed for 33 MHz industrial embedded systems requiring large memory and parity protection.
