Motorola MVME162 Board
Oct 21, 2023
The MVME162, a single-board (SBC), implements a Motorola 68040 or MC68LC040 CPU with memory management and floating point units embedded(only in 68040 models). The MVME162 itself is a single-height 6U VME board. This board was equipped with most of the I/O needed for full computer functionality, including RS232, Ethernet and SCSI(not all models has SCSI or/and Ethernet built in). The external I/O was implemented via the P2-VME connector at the back of the board which became standard in the following MVME1x7 CPU boards. Several breakouts were available, Motorola's 712 boards were the most widely used ones. The MVME162 boards became very popular in industrial computer environments. The board configuration and component will vary depending on the generation.
