which ones? and where did you get them?
i must say of all the games i've played, one of the games i
enjoyed most was DOTT...
there's another one which i played on my old 386-SX25 which i
really enjoyed was Syndicate
all lucasarts adventure games!!!
first download the mac version of SCUMMVM (script creation
utility for maniac mansion virtual machine)
http://www.scummvm.org/downloads/
then go to piratebay or google and search for your lucasarts
adventure games.
SCUMMVM will run like an emulator. 
DOTT in fullscreen 24" glory!!!
