-/**
- * The Screen (memory map).
- * Functions exactly like a 16-bit 8K RAM:
- *    1. out(t)=Screen[address(t)](t)
- *    2. If load(t-1) then Screen[address(t-1)](t)=in(t-1)
- *
- * The built-in chip implementation has the side effect of continuously 
- * refreshing a visual 256 by 512 black-and-white screen, simulated 
- * by the simulator. Each row in the visual screen is represented 
- * by 32 consecutive 16-bit words, starting at the top left corner 
- * of the visual screen. Thus the pixel at row r from the top and 
- * column c from the left (0<=r<=255, 0<=c<=511) reflects the c%16 
- * bit (counting from LSB to MSB) of the word found in 
- * Screen[r*32+c/16].
