Does anyone have Datasheet or the pinouts for an AY1-5051 Fixed Modulus
Divider chip? I can't find them on the internet. It was made by General
Instruments (later Arizona Microchip) and is a PMOS technology.

I am trying to repair a 1960's Elka organ for an 82 year old friend. He
has had it
since nearly new and it has been reliable until now. He would rather
repair than
replace.

TIA
Gerry






Is it only 3 octaves or would there be 2 of the 5051? for more octaves?

Could you note the model number and any chip datecodes , or dates on
capacitors etc
