> Second, can anyone help get this loading on Mac OS X? I've used SPICE for decades, but it's always such a hassle to deal with libraries, symbols, and all of the manual configurations. I found a YouTube video online, but it's 20 minutes long and involves a great deal of manual editing of the SPICE files just to get different libraries working in LTspice.<br>

> Finally, I did seem to get the simulation to run in LTspice after I manually edited the SPICE directive to point to the full path of the 74hc.lib file that I installed, but the output waveform on the sawtooth capacitor was a steady +5V. The pulse input to the counter was so dense that it slows down the whole user interface as it draw 5 seconds of clock waveform. Maybe my 2.3 GHz laptop isn't fast enough?<br>

</span>Ah I guess you'll be needing the symbol libraries as well. The LIB<br>
file goes into<br>
\lib\sub<br>
and the symbols go into<br>
\lib\sym\Digital\74HC<br>
<br>
I am in the US this week on business and won't be back until the<br>
weekend, so I'm (a) jetlagged, and (b) my install file archive is on<br>
my lab machine at home.<br>
<br>
For reference, I am running LTSpice on a Delorean slaptop with a 2.1<br>
GigaMutz Dumbtel CoreBlimey Eye7 and it simulated reasonably ok for<br>
me.<br>
