Interesting.... the particular Zenith Z-386 was purchased through Columbia
University in the summer of 1988. It arrived with only 1 Mb of ram (the
system was ordered with a base 2Mb), the second Mb arrived six months later.
At this point in time, we could finally run Windows/386 v. 2.0 (which was
shipped with the machine and was now obsolete! v 2.1 released in October of
1988). Or, should I say, we could install Windows/386 v. 2.0. It would not
run until we upgraded (at a cost of $50 or $100) to Zenith MSDOS 3.3 plus
- which caused all sorts of newfound incompatibilities.

Finally, (Jan. 89) we installed IBM PC-DOS 3.3 ($100) and purchased
the current version of Windows/386 v. 2.1 ($195). At this point in time
we discovered that the 31-khz video adaptor was NOT vga compatible.
The local dealer was useless, the factory direct people weren't much better.
Giving up on Windows/386 v.2.1, we tried installing Windows/286 v. 2.11
this could at least run at 640x480 resolution BUT never properly switched
tasks (to standard applications - the [alt][tab], [alt][esc] sequence 
NEVER worked).

Come, December 1989 the video board was scrapped - a Video 7 1024i replaced
it (true VGA), Windows/286 still didn't task switch... March of 1990,
the machine was replaced with a Swan 386sx clone from Tussey Computer
Products, the 1024i video board was retained. All compatibility problems
miraculously disappeared !

The Zenith *WAS* a boat anchor.
