Hang on a minute! I
do have the rear side of the attack disk!!
I'm not sure if it's from OLC or from the ACM Reloaded I put over OLC, but I noticed a little red wedge in the bottom right of the Observation periscope. I clicked it, and suddenly the view is filled with the attack disk. But it isn't the attack disk with the two clear sliders, no. This one has what looked to me like a circular slide rule.
I brought up the attack disk manual you linked, and sure enough it matches perfectly with the
reverse side of the attack disk.
Time for more learnin' for me!
