	If you have a Mac, you can enjoy Core Wars with 4 simultenious
fighters and window with debugger.  It's called Core! and it includes
complete specs of Redcode.  The source is available via anon ftp
to you-know-if-you-are-a-mac-user-with-usenet-connection sumex-aim.stanford.edu
and its directory is info-mac/game.
	Since it's possible for me to convert Redcode manual to pure
text and post here, I'll do so upon request.  But I'm too lazy to move on
now.

	I still haven't seen greater fighter than imp.  Some beat imp sometimes
but not for all conditions...
