[GreenKeys] HAL ST-6 - which was is up?

[Paul Heller]

I finally got my hands on an ST-6! After a long time looking for one.  
I'm almost ready now for RTTY.

I asked the person I bought it from to remove all the boards and mark  
where they went, so that they would not come loose in shipping (this  
happened to me once before and there was a bit of internal damage and  
a non-functioning unit, which I gave to another ham).  He removed the  
boards, and he did a great job in packing it.

But he did not mark the boards! And the orientation in the edge  
connector is also unknown


I have seven boards, and eight slots.

Can anyone help me figure out the order and orientation?

Thanks

73s.
