GALasm


From the GALasm documentation:


Introduction
------------

GALasm was created simply because there were no other
freeware and portable GAL assemblers. His assembler
core is basically the one of GALer, a GAL developer
environment for the Amiga platform. I was unable
to get in touch with his author to get the permission to 
do the port, so just a word from him will be enough to
stop my development.
