I created a circuit about 30 years ago based on Forrest Mims's radio shack mini-notebook on operational amplifiers.
The circuit produced positive voltage when momentary switch "1" was pressed and a negative voltage when momentary switch "2" was pressed.
Power supply was 12 volt and might have been a dual supply of +12 volt and -12 volt.
I found this "simplified" circuit when I searched for a "2 position operational amplifier latch circuit".
I do recall the circuit was very simple with few components and as I recall one op amp.
I think this is close.
Would someone please fill in the details so I can build and use this again.
My 30 year old memory; well, isn't.
Thank you in advance.
