I don't think it has, it is a rather old "analogue" church organ. 2 manuals with full pedal board and a decent range of voices, but it can't compete with the modern breed.
It has to go

If it were mine, and it could still be played (keys and pedals work adequately) I would consider a retrofit project.
You need a switch attached to each key and pedal. That may exist if it is electric, worst case if this is pneumatic you end up buying 145 reed switches (61 great, 61 swell, 24 pedal).
Then you need a MIDI out for each. Cheapest way, buy three 61 key electronic keyboards. You don't care about sound or touch, all you need is MIDI. Say $50 each. They'll fit inside your console, nobody will see them. All you need is to wire each organ key or pedal to one of the keyboard keys.
You need a MIDI to PC interface. Mine was about $40, I don't know if you can daisy chain or you'll have to buy one with multiple plugs.
You need a fairly fast laptop to run Hauptwerk software. This has some really impressive cathedral organs modelled with all their stops. If you don't have a laptop, you're going to spend about $2000 here. And of course you want the sound going to a decent amplifer and speaker system, which you may already have.
So, keypress connects to cheap keyboard, which outputs MIDI ON signal to PC, which converts to sampled organ sound from Westminster or whereever your favorite is, and sends to your speakers.
There are other ways, you could use a hardwired organ sequencer instead of the laptop and software.
