TRS-80 model III - The Grafyx Solution installation

[matsondawson]

Hi guys,

I've picked up a model III that has a "The Grafyx Solustion" board in it, but one of the wires has popped off. It's labelled U17, but there is no sign of soldering on U17 previously, so I'm not sure what pin it would go on.
Is there a manual somewhere?

Cheers.
Matt

Thanks to Tezza, I have it figured out now. U17 is optional, and used to prevent clear streaks during updates.
