VMEbus (Versa Module Europa bus) is a
computer bus standard, originally developed for the
Motorola 68000 line of
CPUs, but later widely used for many applications and standardized by the
IEC as
ANSI/
IEEE 1014-1987. It is physically based on
Eurocard sizes, mechanicals and connectors (
DIN 41612), but uses its own signalling system, which Eurocard does not define. It was first developed in 1981 and continues to see widespread use today.
