Thanks very much for your help. I've managed to get jamvm installed on
Debian Sarge after a few tries:
apt-get install jamvm
[failed with some error messages about missing libraries]
then
apt-get --fix-missing install jamvm
[failed again]
then
apt-get update
finally
apt-get install jamvm
and despite some complaints it appears to be installed and working
(ftp'd a test class to the board and invoked jamvm.
I'll look further into J2ME too, but I seem to recall there were some
class issues that put me off it earlier.
