[GreenKeys] loop supply - part 2

[Virgil Bierschwale]

Thanks to you folks, I now understand how the loop supply is wired in.

The model 28 KSR I have has a LESU with no part number, and broken wires,
things like that.

So I want to wire the loop supply directly to the selector magnets (unless
there is a better way).

There are two selector magnets, so there are 4 wires.

They appear to be orange, yellow, brown, and white.

Any advice on how I should hook up the loop supply here?

It's been a long time, but I'm assuming one selector magnet is for the
typing unit, and the other is for the keyboard.

My long time goal is to hook this up to an arduino so that I can send
reports to it periodically.

Thanks,

Virgil
