- * Read-Only memory (ROM) of 16K registers, each 16-bit wide.
- * The chip is designed to facilitate data read, as follows:
- *     out(t) = ROM32K[address(t)](t)
- * In words: the chip always outputs the value stored at the 
- * memory location specified by address.
- *
- * The built-in chip implementation has a GUI side-effect, 
- * showing an array-like component that displays the ROM's 
- * contents. The ROM32K chip is supposed to be pre-loaded with 
- * a machine language program. To that end, the built-in chip
- * implementation also knows how to handle the "ROM32K load Xxx"
- * script command, where Xxx is the name of a text file containing 
- * a program written in the Hack machine language.  When the 
- * simulator encounters such a command in a test script, the code 
- * found in the file is loaded into the simulated ROM32K unit.
