It rescues *ME* about once a day when I do Z-100 specific stuff, and I use it as my general MS-DOS reference as well. As for your question... I have never had the console refuse output... I can dig through PUP some more if you want to me too (and no one can answer off the top of their head). Did you ever get the S-100 modem to work? Drew
