Sorry, in my previous article I forgot to include the m-ridge.h and s-ros.h files I have. Here they are. Remember that they are completely naive, and I did not look at ridge docs to decide on what to put. --- m-ridge.h --- /* m- file template. Copyright (C) 1985, 1986 Free Software Foundation, Inc.

I have not tried to bring up emacs on my Ridge 32C but one thing is immediately apparent. The Ridge is a big-endian machine.
