I just dug up the IBM flyer for the Displaywriter version of Logicalc (which
I wrote way back when). The machine requirements are:
1 Model 6850 Electronics Model with at least 128K bytes of main storage
...
The UCSD p-System Runtime System (5608-MS1) or the UCSD p-System Development
System (5608-MS2).
Since the p-System did run on 8-bit processors, this doesn't really answer
the question, but the 128K requirement would mean either a 16-bit processor
or bank switching.
There are some references on the net that say 8086, e.g.
http://www3.sk.sympatico.ca/jbayko/cpu3.html#8086, and this guy claims to
have ported MSDOS to it for Phoenix:

I thought it
was an 8085. I believe there was CP/M for the
displaywriter, and I remember seeing a flyer about a DOS upgrade, though
I dpon't know if it ever materialised.
It's certainly possible that there were earlier models using an 8085; I'm
positive that the model I worked with was an 8086 because I ported some of
that software I mentioned. I guess the original poster might have either.
