As a former Kaypro user I 
can testify that their 
8-bit CP/M 2.2 boxes never 
used 8085s -- they used 
Zilog and Mostek Z80s.  
Before going to a strictly 
PC architecture, Kaypro 
did sell a non-PC model 
with a 16-bit CPU and non-
IBM monochrome video 
running MS-DOS, so perhaps 
there was an 8085 in there 
somewhere in that one, but 
I doubt it.
