Why don't you just enter the equivalent schematic from the data
*** (page 3 of the pdf - National 1995)? It only has thirteen
each of transistors and resistors (wouldn't take more than about
thirty minutes to get something up and running).

And why aren't you using Linear Technology's LTspice? It's free,
unlimited, completely general purpose and is faster and works
better than either Pspice or ICAP.

Before I found LTspice I was a die-hard fan of Pspice (I have no
affiliation with Linear Technology, btw).
