I had a model submarine. I didn't want to do a direct connect from it
to the Z80 bus for controll. I couldn't afforad to build an
opto-isolator for it. So I used the TV screen. I covered the top half
with photo-sensors. Had my program put black blobs on the appropriate
spot on the screen and that did whatever to the submarine. Looked wierd
but at least a power short on the sub couldn't fry the computer.
