You can visit the virtual Apple II GS website here:
www.virtualapple.orgAs far as the IIGS goes, it's the computer the Woz really wanted - he was/is an 8-bit guy at heart! The IIgs is kind of like...hmm, maybe what the C65 would've been had it been perfected. The last word in 8bit desktop systems.
I've seen some tricked out with SCSI, big hard drives, video cards, network cards, USB, etc. etc.
Grab it and see how far you can push it!
