Motorola Single Board Computers is Motorola's production line of computer boards for embedded systems.[1] There are three different lines: mvme68k, mvmeppc and mvme88k. The first version of the board appeared in 1988. Motorola still makes those boards and the last one is MVME3100.[2]

NetBSD supports the MVME147, MVME162, MVME167, MVME172 and MVME177 boards from the mvme68k family,[3] as well as the MVME160x line of mvmeppc boards.[4]
OpenBSD supported the MVME141, MVME147, MVME162, MVME165, MVME167, MVME172, MVME177, MVME180, MVME181, MVME187, MVME188, and MVME197 boards. Both the OpenBSD/mvme68k and OpenBSD/mvme88k ports were discontinued following the 5.5 release.[5][6]
A quote from the NetBSD port page: NetBSD/mvme68k is the port of NetBSD to Motorola's 68k VME Single Board Computers (SBC). The first Motorola SBC was introduced in 1981. Motorola has continued development on 68k and PowerPC based SBC VME modules.
