I assume you mean 256kB of RAM. The footprint on some of the small simgle-chip micros is pretty small According to: http://www.iro.umontreal.ca/~feeley/cours/ift6232/doc/pres2/jvm-for-very-small-devices.pdf the squawk footprint is pretty tight. > > I will talk to the Sun Labs people running this project to see what the > status of access to the code for Squawk is.
