Sorry to drag this back up... Playing around with an A600 this eve, and *most* of the demos I've tried work, albeit from my old floppies.
State of the Art
9 Fingers
Exodus (by Ninja/Agony, a real nice underrated demo)
Spazalytical
Hallucinations and Dreams
Desert Dream
Batman Vuelve
Revelations slideshow (mind-blowing OCS gfx IMO)
So far two demos don't run, but that may be my accelerator.
Another problem you may be having, some games (a few Pinball titles, Lotus 2 & 3) and demos (2nd half of Desert Dream IIRC) need some "fastram" in the autoconfig space, or they won't run. Aside from an accelerator, I'm guessing the only option for the A600 is a PCMCIA RAM card, and/or WHDLoad (if it works with only 2 megs).
For me, the biggest issue is I need another motherboard... unlike my A1200, I can't seem to get this thing to stay in PAL mode reliably. :/ Real annoying when a demo kicks back to NTSC halfway through.
