Back in 1986 the team that created the Rombo VIDI digitiser and software were far-sighted enough to allow customers the option (via the VIDI RSX program) to create their own programs to modify the output from the hardware; the three BASIC animation programs below are examples of this.
Two of these programs are original and the other, "ANI", appears to be a user modified version of one of these.
I Run the three programs and List them.
