The MVME187, a single-board computer (SBC), was the first system from Motorola to implement a 88000 CPU, in this case the 88100. It is, besides the actual MPU, almost identical to its m68k-based cousin MVME167; both can use the same peripheral and RAM boards. The MVME187 itself is a single-height 6U VME board. Memory has to be placed directly on this board via so called mezzanine boards, which were available in two different types and several configurations:
These boards can be mixed when using Motorola System V/88 Unix. Up two two boards can be placed on the SBC;
just one mezzanine board and the SBC take up one VME slot. Two mezzanine boards and the SBC take the space of
two VME slots.
The external I/O was implemented via the P2-VME connector at the back of the board. Several breakouts were
available, Motorola's MVME712 boards were the most widely used ones.
