Needing to unshrink some shk archive on a PC

Ok, I've been all over the asimov site to no avail. I haven't found
anything yet I can run on the PC, or through the AppleWin emulator to allow
me to unSHK files.

I am looking for a particular Nibble game I fell in love with years ago,
called Quintic. I've found a bunch of Nibble Disk archives, but they're all
SHK'd....and I can't unshrink them. :(

Can anyone give me any hints as to where to go? What to try?

Far from being a computer dummy, I started on the ][+ many moons ago...but
haven't messed with one in about 10 years now.
