I have run Squeak versions 1.1 through 2.x on a Powerbook Duo 280 and  
can tell you that it is very, very slow.  Mine currently has 40MB of  
RAM, but even screen redraw is pretty annoying.  It is better when it  
is docked and I can run in 256 colors or Thousands of colors, but on  
the built-in display (grayscale or B&W) the machine just crawls.   
Even typing text takes caution, as each character I type shows up on  
screen slower than a 300 baud modem.

If warnings like these still don't dissuade you, I would recommend  
using the version 1.31 image & VM.  I was running System 7.5.5 with  
all patches.  (Come to think of it, I don't know if 1.31 has any  
decent sound support...  I can't remember)

(Also, I got the 36MB memory module for the Duo on eBay for very,  
very cheap.  You may want to look into that, though if you are not in  
the United States you might have to pay large shipping fees.)
