Gee...  what about servos like you find in RC equipment...

Just a tad of engineering and you can emulate the original basic software
with enhancements to use the servos to replace the cam...
It is a great starting off point for those who want to play with robotics as
you already have the basic platform...

I guess I am a bit of a fanatic... but then I do have SEVERAL vintage Mac
machines...  and comodore... several CP/M machines... ect
