Latest find : IBM display writer

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., and this guy claims to
have ported MSDOS to it for Phoenix:
