In our initial program, there are only two interrupts per frame: one mid-screen to prepare for drawing the board and status line, and one at the bottom to reset the display for the logo next frame. This meant that the interrupt handler could decide what to do simply by checking the current scanline as reported by the $D012 register; if the value was over 127, do the end-of-frame work, and otherwise do the mid-frame work. That simple test required only a single instruction, and while the exact value of $D012 might vary, the test was broad enough that it didn’t have to worry about it.
