The VMEbus Specification Rev C.1 does not list an expansion for the letters, but in discussing the history of the VMEbus on page v, mentions that the first VERSAbus cards were called VERSAmodules. At the time that the VERSAbus specification was being nailed down (*after* the first cards were designed, of course), Motorola's European Microsystems Group in Germany designed a Eurocard version they called the VERSAbus-E; shortly thereafter, Motorola, Mostek, and N.V.Philips/Signetics all agreed to support it, and renamed it VMEbus. "VERSAmodule Eurocard" would therefore be a good candidate. V M E
