I have just uploaded the keyboard maps to ftpnetbsd.org. They can
be found in 'pub/NetBSD/arch/atari/utils.NetBSD'. Be sure to get
the README too.
Because of a bug-fix in the latest kernel (that you're all running
now ;-) ), I is also advisable to get the updated 'loadkmap' program
for those who currently use the old program. In the previous version
of both kernel and program, you lost the new mappings each time you
logged-out on one of the virtual consoles. This won't happen now.

Leo.
