Drawing Schematics on the Mac

[R.Fahl]

I'm about 90% finished redesigning the Electronotes Cross Product Module.
I've replaced all of the antiquated TTL with CMOS.  I've got it working
pretty well so far, just need to make a few minor mods.  Pretty unusual
sounding unit.

I'd like to document this update.  What is a decent Mac program for drawing
schematics?

"The complexities of developing a jet engine were sometimes overcome in
almost simplistic ways; when the 004B-1 began to have vibration failures in
the turbine buckets, a professional musician was hired.  With his perfect
pitch, he could determine the natural frequencies of individual blades in
an assembled turbine wheel by means of a violin bow.  His gentle bowing led
to the solution of the vibration problem by tapering the blades slightly to
increase their natural frequency, and by reducing the operating RPM of the
engine from 9,000 to 8,7000 RPM."  From "Messerschmitt ME 262 Arrow Into
the Future" by Walter J. Boyne
