John,

In the spirit of bringing this post back on topic; you are the guest
speaker.

Tell us more of your "intimacy" with the 555 timer. You are after all
a electronics legend in your own right.

Since being "a" (should be 'an') "electronics legend in your own
right" would be a compliment, I'm sure you meant: "an electronics
legend in your own mind", no?

Bless us with your knowledge.

Well, OK, (blushes)...

Here's an ASCII schematic of a 555 which shows its basic functions.
View with a fixed pitch font like Courier:

What would like to know about it?
