The Service Manuals for The MK1, 2, 3 Version of the GS 1200 is nearly the same without two points. In the MK3 Version the Motor control Board is different. There is working a BA6301 IC. On the MK1 and 2 it is a µPC 1002c. The second Point is that the Take up and rewinding Motors are runnin with 20V. In the older Versions only with 8V. So the Transformer and the Board of the two Motors are in this different too. In the Mechanial Section the MK 3 Version has the backwards Loop in front of the Sound Heads.
