There is a DOS "command line" version for Linux that works well - you
should be able to get it going on a 386 w/o much problem.  Look for RedHat
5.2 to 6.2.  With that setup you could run the graphical version also.

The 386 must have a numeric coprocessor to work  or you must compile
floating point emulation on a different system.

There are quite a few distros that focus on such a small system. Try
PeeWee Linux, TinyLinux, tom.s root boot. 

Beginners projects they are not. Do some research and check out the
Linux HOW-TOs. They are invaluable.

You're describing DOSEMU (Dos Emulator), which I myself use to run
InstanTrack (my all time favorite satellite tracking software) on my main
Linux system.  

I don't think, however, that emulation answers the question.  Performance
is going to be slower, because all O/S commands have to be translated into
host system and then run, rather than run natively.  There's also the
problem of making sure hardware-level resources are correctly configured
in the host system, made available to the emulator, and then configured
correctly in the emulator.

Raw system performance is important when you're doing any kind of DSP.
Soundcard based digital modes are DSP.  As one limited data point, I
recall first using a Pentium 120 system to try to monitor SSTV
transmissions. Performance, frankly, was terrible.  The same software on a
PII-350 ran fine.  This was using Win95.  I haven't tried this with Linux.
I don't know if there are any DOS-based PSK31 programs.

Graphical-based systems will run slower on the older hardware.  More
ram can help.  But Win 3.1 or X-windows on a 386 is still going to be
SLOW. Sound cards for older systems may also have problems.

These older systems are FINE as terminal displays and for many dedicated
applications.  If you have an external terminal unit that supports your
desired mode, it may be fine.

Sorry, I said that wrong.  There is a LINUX version that doesn't run under
the window environment.  It comes with TWPSK (the window version).  It
does a good ASCII version of the scope and everything so it isn't too bad
to use (not as pretty but works FB).
