RCA Studio II

Boots the RCA Studio II from its authentic 2 KB system ROM. The default loads the Hockey cartridge, which drives the console beeper as it runs, so click Sound to hear the ~500 Hz tone gated by the 1802 Q line. The other cartridges beep on their own game events (Pac-Man on start, and so on). Player A is the number row 1 to 9 and 0; Player B is the numeric keypad 1 to 9 and 0 (both are the console's two ten-key pads). The bare "Built-in games" config boots the system ROM to its blank selection screen; press 1 to 5 to start a built-in game. Add ?debug, or click Debug, to single-step the 1802, set breakpoints on a PC and watch a memory cell for writes. Click the screen first so it captures the keyboard.
