History Check -- First CMOS mainframe

On my wandering around, I found the following claims on the Unisys
"history" web page (http://www.unisys.com/about__unisys/history/index.htm):
"1993 Unisys introduces 2200/500, the first mainframe based on
complementary metal oxide semiconductor (CMOS) technology."
Wasn't the ETA-10 CMOS-based? (Not to mention the whole subject of
"What's a mainframe?")
"1989 Unisys introduces Micro A, the first desktop, single-chip mainframe."
I don't know what to make of that claim. What's a mainframe. From what I
can gather, the Micro A was pretty much a plug-in coprocessor PCB in an
otherwise x86 box that booted OS/2.
Comments? Anyone on the list a Blue Bell veteran who can give the real
scoop on the Micro A?
