Hello Tom,
it is absolutely forbidden to remove these screws : they keep aligned lenses and vertical slider of the optical zoom.
It would be a nightmare to adjust the whole zoom system !
I don't think that the screws that held your system are inside microscope housing :
because the two parts of the microscope housing (top and bottom) are kept together with 3 long screws that you access at the bottom side.

But this is not what you need to do :
I think (in fact, I am pretty sure) that the black plate that hold the motor is screwed with the same 2 screws that hold the microscope housing to the microscope holder.
These 2 screws are circled in blue on the photo.
You have to remove the black rectangular part to see these 2 screws...
