OK - I've spent a few hours looking at this, and these are the results.
(To the rest of the developers: This is an update to yesterdays email)

It is possible to run GEM (3) using 'xdos'. It should be possible to run
it using 'dos', but only if you have a supported graphics card. However,
I've only been trying using 'xdos'. 

First things first: You'll want to be using one of the developer copies of
DOSEMU. No version of DOSEMU has decent support for any 16 colour mode,
but the developer versions have support for the 2 colour (monochrome) VGA
mode. Feel free to try the 16 colour modes but you'll find the following:
1) incredibly slow screen update
2) Blatantly wrong colours (GEM is *not* supposed to be red ....)
3) Poor screen refresh resulting in badly drawn/covered/hidden items
4) Illegible fonts
The monochrome VGA works perfectly.

For those who don't have GEM installed you can find links at
http://www.deltasoft.com/. I found I couldn't use any of the installable
versions but I did work out a way to install the disk images without
having to make a set of floppies. This method requires a "real" version of
DOS. It cannot be achieved using the supplied copy of DOS/C.

This is how I installed GEM (using 'xdos'):

1) Copy all the disk images to a single directory, eg 'gem__system' in
        /tmp. The name of this directory *must* be 11 characters long.
2) Change all of the volume labels in GEMSETUP.MSG to the name from 1)
        (Search for HVOL_PTR in the file)
3) Start DOSEMU & map directory in 1) as a:
        (eg 'lredir a: linux\fs\tmp\gem__system')
4) Run gemsetup.exe from a:
5) Select 'IBM VGA Monochrome (640x480) or Compatible'
6) Select 'Bus Mouse (Requires file MOUSE.COM)'
7) Select 'SAVE AND EXIT FROM GEM SETUP'
8) Continue to the end of the installation
9) Upon completion run 'gem.bat' from root directory of your installation
        drive.

[1) & 2) are necessary because GEMSETUP uses the disk labels to check if
it has the correct disk]

Then you should be able install any other applications you want. For most
of these you can probably just copy all the disk images to a single
directory and 'lredir' this directory as a: drive. (Most GEM applications
expect to be being installed from floppy) If you are prompted for another
disk just continue. 

I have installed (and tried) First Word Plus and GEM Publisher -- both
appear to work fine. I haven't tried printing yet. The version of First
Word Plus that I tried (V2) wanted it install GEM Paint but didn't include
the disks. Doesn't appear to be a problem yet.

For reference, I've tried to get 'Artline 2' working (it comes with a
version of Gem/4). However, it won't run under DOSEMU. (It just terminates
DOSEMU with an exit value of 2.)

I've also run ViewMax (3?) but haven't yet remembered enough of my DR-DOS
to be able to persuade it to read the INI file, so it insists on using the
VGA-16 mode.

Apart from that its nice to have GEM back -- I last had GEM back in '92
when I ran it under EGA. ViewMAX was more recent -- Somewhere I still have
my original DR-DOS 4 disks.

PS. For those desperate to use a higher resolution then the trident
drivers listed on John Elliott's WWW pages
(http://www.seasip.demon.co.uk/Gem/) work with xdos, but, because they use
16-colour mode you'll have the same problems outlined above)

PPS. John (and everyone until he fixes it 8-) - trident have lowercased
their URL.
