Actually, the classic astable mv usually has a genuine hangup state,
both transistors saturated.

Return the base resistors to the collectors of their respective

sarurating and will ensure reliable starting.

 
Right. It makes the transistors go linear if it's not oscillating.

Yes,  I discovered that in the early 1970's when I first started using
multivibrators.  I don't remember seeing it documented anywhere.
