<DIV><FONT size=2>Transistor-Transistor Logic! Sorry, it came back to
me. Actually, TTL was one of the first digital logic circuits or
integrated circuits (ICs). The transistor allowed the removal of a lot of

<DIV><FONT color=#000080 size=2>Hee hee, you younglings need an old fart to
tell you about TTL. Except, I am having a senior moment and can't

Logic. </FONT></DIV>
