SUMMARY: PC emulation

Original question:
One of my users (my boss) wants to run DOS applications (MS Windows 3.0, TimeLine, CorelDraw,
Supercalc etc.) on a SUN (we're using SLCs, ELCs and SS2s).
I've heard about DOS Windows, SoftPC and XDOS.
I need fax numbers of the suppliers for SoftPC, XDOS and anything else except for DOS Windows
because I've got already an offer...

According to the answers, SoftPC is much better than DOS Windows.

Although some said they were happy with DOS Windows, the general consensus is
that DOS Windows 1.0 is a slug. It supports CGA graphics at best. DOS Windows
1.0.1 is a bug-fix release but doesn't add any functionality or performance

Sun does have a bug-fix version of DOS windows out (version 1.0.1).
We have not purchased the upgrade, however, because Sun wants
$360 for it. Considering that we only paid $400 for it new, I
say kill the bastards.

SoftPC is $600 for the Sun. Considering that SoftPC is supposed
to run everything, including MS windows, and it emulates EGA (and
soon supposedly VGA) as opposed to CGA for DOS Windows, I would
forget about DOSWindows. Sun seems to have forgotten about
DOSWindows, whereas Insignia seems to specialize in DOS
emulators. I would pay the extra $240 and get a real product.

SoftPC has EGA, CGA and Hercules emulations.
Can access IPC's 3,5" diskette drive.
Can have one to two PC hard-disk's emulated on Unix filesystem.
Those "emulated" hard-disks look under Unix filesystem as files.
So you can't access files on those disks from Unix.
Instead you can access Unix filesystem directories from SoftPC
as emulated PC drives. You just give command:
  C:> net use h: /home/aro
And then you can access drive H: from SoftPC and tranfer files between
SoftPC and Unix.
There's two utilities: unix2dos and dos2unix , to change ascii files
between DOS and UNIX formats.

SoftPC is just an emulator so it's not fast, but one can run DOS software
with OpenWindows. More RAM would help... I tried to run Microsoft Windows 3.0
but it was too slow for me. With MS-WORD 5.0 the speed is OK.
Both SoftPC and DOS Windows are too slow for running MS Windows 3.0 and
other graphics apps.

and more.
