Z3VR Demonstration: Program operation

Z3VR is a VR simulation of Konrad Zuse's Z3, arguably the world's first computer. The project is currently unreleased; if/when it is released I will update the description of these videos to include a link.

Some info on the shown program:
The Z3 does not feature an instruction for the modulo operation, this program simply emulates it via a floored division.
The first film strip takes in an arbitrary non-zero input and turns it into 2^14. The second then takes the actual arguments A and B and divides them, adds and subtracts 2^14, multiplies the result by B, and subtracts that from A, leaving the remainder as the final result.
