[GreenKeys] Unidentified PCB in a 33ASR

[tomas at tlec.se]

I'm not sure if it has 3 or 4 positions, there is no text on the hood, and I
haven't got that far with the re-assembly   yet.
Doing a full schematic of it now, since there is more discrependencies
compared to the schematic I got.
The front switch is a 7-pole 2-way switch and not as in the drawing a 4-pole
2-way switch, although only 5 positions is used.
There is two switches with lamps on the metalic plate on the right, labeled
"Leser/Schritt" and Auto/Man" connected to J5
On the drawing thay are labeled "Motor" and "Schritt".

J2 and J3 are complete empty

I have a 50Hz machine, but this card is not part of it.

Does the lever next to the reader have 4 positions i.s.o. 3 positions?
