The Motorola MVME188A Series VME Single Board Computers are manufactured in several models.

The basic MVME188A includes only the System Controller (SYSCON) board and the 25 MHz Main Logic (CPU) Board.

It will not work without adding one, two, three or four memory boards; and one HYPERmodule mezzanine module containing the RISC chips.

Enhancements to the MVME188A (over the MVME188) include single-cycle refresh to minimize VCC noise, 

increased onboard bypass capacitors, and onboard shielding of high-speed clock lines.

In addition, the MVME188A has been enhanced with orthogonal data/

address line layout to reduce crosstalk as well as changed from CMOS to TTL drivers to reduce overshoot/undershoot.

The MVME188A offers improved RESET functionality.

It performs a full system RESET on MVME188A boards that are not the system controller and are memory mapped at a location other than $0.

Both supervisory mode and user mode accesses are not permitted as well.
