[GreenKeys] ST-3 Demodulator ?

[Norm]

I have acquired from a "Greenkeys" friend two units that appear to be some what Mainline ST-3 units from the information that is on "www.rtty.com", one unit which appears to be the Demod side  has the "Autoprint and Motor Delay", and the "FSK Driver and Keyer" card that doesn't have Q1 and Q2 that shows in the FSK Driver and Keyer diagram, and another plug in card has two torrid coils, three screw pots, written 2975, 2295, 2125 on them, and seven transistors, which I assume to be a older Main Circuit (input,limiter, discriminator and detecter), that I don't have a diagram for.  The other unit appears to be the Mod side, one card has three torrid coils together and two torrid coils together and no diagram for this either.  These two units have 36 pin male plugs on the end of the unit. Would these to units plug in to each other?

I hope you can make sense of this, because when I read it back I'm not sure I do.  If you can't please e-mail me back.  I would appreciate any help I can get.

Thanks
Norm
