This lab test article is fascinating. It includes Plus accelerators and the first generation of SE accelerators only! Nothing tested had a 68030 or provision for additional RAM. The tests pre-date implementation of the 68030 in the Macintosh IIx (September 1988) by six months. These accelerators pre-date  MODE32 (1991) and 32bit addressing by about three years.
