I'm not aware of any Amiga model-specific emulators. I use E-UAE, the
port of the free {UNIX|Ubiquitous|Universal} Amiga Emulator for UNIX
and UNIX-like operating systems which can emulate a variety of
different Amiga models depending on the ROM images used. You can
obtain ROM images by dumping them from your Amiga, by purchasing them
from Amiga Forever [1] or by illicit means. Amiga
Forever is more than
just ROM images, it's an easy to use emulator targeted at
those who
are less technically inclined. There are a variety of tutorials on how
to install, configure and use E-UAE and UAE on the web and since I
don't know anything about your computer, I'll leave you to search for
the information you need.
As for your 600, have you considered plugging it in, connecting it to
a display and turning it on? :)
