ANSWER: 8085 Microprocessor Problem, Multivibrator

Bistable Multivibrator

In the basic analysis there is no difference in the transistors actually.
Think of transistors as power on and off switches. Just a glorified this : _/ _

So lets say we have transistros Q1 and Q2. When Q1 is on, that is: _._._
it shorts the high voltage signal to ground, and its output goes to zero.
Zero goes in to the Q2 keeping it off, that is _./ ._

Keeping the transistor open does not ground high voltage signal. This keeps output at high V. Which goes to input of Q1 and keeps it on all the time. Now this is a stable state, similar state which will be stable can be acheived by Q2 on and Q1 off. For two stable states it is bi stable
multivibrator.

I found a link to a good teaching aid for this. You may try
